120<H2>3. Items for migration of the user code</H2>
121
122Listed here is some relevant information on developments included in this
123release, some of which may require migrations (mainly for users of advanced
124Geant4 features) in order to upgrade from release 9.2 to release 9.3.
125Note that for all users a full re-installation of libraries (or a full
126recompilation) and a recompilation of user applications is required.

131<UL>
132<LI>A new method <TT>CheckParticleList()</TT> has been added to
133    <TT>G4VUserPhysicsList</TT> to check the consistency of the list of defined
134    particles before instantiating the physics processes. For example,
135    <TT>e+, e-</TT> and <TT>gamma</TT> should exist if any electromagnetic
136    process is simulated... A fatal exception will be thrown if any particle
137    type mandatory for the simulation is missing.<BR>
138    It is possible to skip this check, by making use of the method
139    <TT>DisableCheckParticleList()</TT> from <TT>G4VUserPhysicsList</TT>.</LI>

142<P> </P>
143<B>Low Energy Electromagnetic physics</B>
144<P> </P>
145<UL>
146<LI>All Low Energy Electromagnetic Physics process classes have been entirely
147    redesigned (migrated) in the Geant4 toolkit in order to offer to users a
148    coherent approach for the modeling of electromagnetic physical interactions.
149    The software design is now common to both 'standard' and 'low energy'
150    electromagnetic modules. These changes affect Livermore, Penelope,
151    ICRU'73 ion and Geant4-DNA Physics. Users are invited to modify their own
152    physics-list(s) in order to use these new processes and models.
153    The web page indicated below describe how to use these new processes and
154    models, with examples of physics list implementations and new features of
155    the adopted common design:<BR>
156    <A HREF="https://twiki.cern.ch/twiki/bin/view/Geant4/LoweMigratedProcesses">https://twiki.cern.ch/twiki/bin/view/Geant4/LoweMigratedProcesses</A>
157    Please note that it is still possible to use previous implementation of the
158    low energy processes for backward compatibility, however, these models are no
159    longer maintained and will be removed in the near future. A warning message
160    will also be displayed when running older low energy model versions.</LI>

163<P> </P>
164<B>Standard Electromagnetic physics</B>
165<P> </P>
166<UL>
167<LI>It is recommended to migrate user custom physics-lists by replacing
168    the <TT>G4MultipleScattering</TT> physics process with the following:
169    <UL>
170    <LI><TT>G4eMultipleScattering</TT> for <TT>e+-</TT>;</LI>
171    <LI><TT>G4MuMultipleScattering</TT> for muons;</LI>
172    <LI><TT>G4hMultipleScattering</TT> for hadrons and ions.</LI>
173    </UL>
174    The former <TT>G4MultipleScattering</TT> still exists in the Geant4
175    distribution but will be deleted in a future release.
176    <P></P>
177    Nuclear stopping power is no longer part of ionization processes, and is now
178    responsible only for electronic stopping power; for simulation of nuclear
179    stopping, a new process <TT>G4NuclearStopping</TT> should be added to
180    custom physics-lists.</LI>
181</UL>
182
183<P> </P>
184<B>Physics Lists</B>
185<P> </P>
186<UL>
187<LI>Qualification for several physics-lists have changed. Several are now declared
188     obsolete. A new category of 'experimental' is used for newer physics-lists or ones with new physics options. Some physics-lists have been removed.
189    See in <A HREF="#lst-notes">Section 10</A> for the details.</LI>

195<UL>
196<LI>The OpenGL Print EPS facility now always depends on the compression library,
197    <TT>zlib</TT>. An internal version of this library is provided for users
198    whose system does not provide the library <TT>libz</TT>.
199    To use this internal version, set the environment variable
200    <TT>G4LIB_USE_ZLIB</TT>.
201    Users who build with the standard Geant4 <TT>Configure</TT> script should
202    not have to worry about this as the environment will automatically be set up
203    correctly.</LI>

224
225<B>Geometry & Field</B>
226<UL>
227<LI>A new stepper <TT>G4NystromRK4</TT> offers better computing performance in
228    integrating the trajectories of charged particles in a magnetic field.
229    It uses the standard Nystrom method and a novel analytical estimation of
230    the integration error. This reduces greatly the number of field calls per
231    integration step (from 10 to 3). It achieves comparable accuracy with
232    <TT>G4ClassicalRK4</TT> in test cases. It can be used only for pure
233    magnetic fields which are not time-dependent.</LI>
234<LI>A  new class <TT>G4CachedMagneticField</TT> caches the value of a magnetic
235    field class, in order to reduce the number of calls to an expensive field
236    calculation or interpolation method. For positions within the chosen radius
237    of the previous position where it evaluated the field, it returns the last
238    value of the field is automatically. It can be used only for pure magnetic
239    fields which are not time-dependent.</LI>

244<LI><U>GDML</U>: it is now possible to customise the reader as well as
245    the writer to treat ad-hoc user extensions to the GDML schema.
246    The GDML writer now also supports dumping of optical surface
247    properties associated with surfaces and materials.</LI>

250<B>Low Energy Electromagnetic physics</B>
251<UL>
252<LI>Software migration: as explained in section 3, all low energy
253    electromagnetic processes and models are now adopting the same design
254    as for the Standard Electromagnetic Physics, for a coherent approach
255    of the modeling of electromagnetic physical interactions.</LI>
256<LI>Livermore Physics: new <TT>G4LivermorePolarizedPhotoElectricModel</TT> and
257    <TT>G4LivermorePolarizedGammaConversionModel</TT> are available for the
258    simulation of polarized photon interactions.</LI>
259<LI>ICRU'73 ion model : the upper energy limit of ICRU'73 stopping power tables
260    was extended to <TT>1 GeV/nucleon</TT> (compared to <TT>10 MeV/nucleon</TT>
261    in the previous release). Revised tables were included for <TT>G4_WATER,
262    G4_WATER_VAPOR, G4_Cu, G4_NYLON-6-6</TT> (all tables provided by
263    P. Sigmund/Univ. of Southern Denmark).</LI>
264<LI>Geant4-DNA Physics:
265    <UL>
266    <LI>Energy range coverage of several Geant4-DNA Physics models has been
267        extended: electron elastic Champion's model from <TT>7.4 eV</TT> up to
268        <TT>10 MeV</TT>; electron ionization Born's model from <TT>11 eV</TT>
269        up to <TT>1 MeV</TT>; proton excitation Born's model up to
270        <TT>100 MeV</TT>; proton ionization Born's model up to <TT>100 MeV</TT>.</LI>
271    <LI>Geant4-DNA models are valid for liquid water only and use now the
272        <TT>G4_WATER</TT> NIST material as liquid water material definition.
273        Users should define liquid water as <TT>G4_WATER</TT> in their
274        application(s).</LI>

279<B>Standard Electromagnetic physics</B>
280<UL>
281<LI>The set of multiple-scattering models has been expanded:
282    <UL>
283    <LI><TT>G4UrbanMscModel92</TT> is the default model for <TT>e+/e-</TT>
284        equivalent to the Urban model included in the previous release 9.2.
285        It is used as the default and in the <TT>Option1</TT> electromagnetic
286        physics constructors for physics-lists.</LI>
287    <LI><TT>G4UrbanMscModel93</TT> is a tuned version of the Urban model used
288        for <TT>e+/e-</TT> in all other physics constructors of physics-lists
289        (<TT>Option2, Option3, Livermore, Penelope</TT>).</LI>
290    <LI><TT>G4GoudsmitSaundersonMscModel</TT> is a new model for <TT>e+/e-</TT>
291        based on formalism developed for Penelope and EGSnrc.</LI>
292    </UL>
293    A new relativistic model <TT>G4PairProductionRelModel</TT> is available
294    for gamma conversion into <TT>e+e-</TT> pair. In this model, the LPM effect
295    is taken into account. The model is suggested for use in high-energy
296    astrophysics applications.</LI>
297</UL>
298
299<B>Hadronic physics</B>
300<UL>
301<LI>Improved and extended the <TT>FTF</TT> model.
302  Improved  its pion absorption on nucleons, introduced Reggeon cascade stage, and added excitation energy calculation. Tuned the model  parameters of nuclear de-excitation and
303  implemented charge-exchange for <TT>pn->np</TT> in elastic and
304  inelastic interactions.</LI>
305<LI>The validity of the pion-nuclear cross-sections in
306    <TT>G4PiNuclearCrossSections</TT>, and the nucleon-nuclear cross-sections
307    in <TT>G4NeutronInelasticCrossSections</TT> and
308    <TT>G4ProtonInelasticCrossSections</TT> has been extended to <TT>100 TeV,</TT>
309    by assuming a constant cross-section at very high energies.</LI>
310<LI>Glauber-Gribov cross-sections for ion-ion collisions are now available in
311    the class <TT>G4GGNuclNuclCrossSection</TT>,
312    spanning from <TT>0.1 MeV</TT> to <TT>100 TeV</TT>.</LI>
313<LI>The nucleon-nucleon and pion-nucleon partial cross-sections used in the
314    Bertini cascade were reviewed and the incorrect cross-sections found below
315    <TT>1 GeV</TT> were fixed. This results in slightly improved agreement
316    with data below <TT>1 GeV</TT>.</LI>
317<LI>The CHIPS model has been extended with hadronic interactions covering all energies for all hadronic particles; in addition    hadron- and
318    lepton-nuclear reactions  are extended to high energies (~TeV).
319    It can be used by choosing the new <TT>CHIPS</TT> physics-list.
320    CHIPS ion-ion elastic scattering model is also now available.</LI>
321<LI>An option was added to allow models for elastic scattering  to be treated in a similar way to inelastic models. Models can now be assigned to the
322    process class <TT>G4WHadronElasticProcess</TT>.</LI>   
323<LI><TT>G4NeutronRadCapture</TT> is a simplified new model which produces a
324    single photon after neutron capture. 4-momentum is conserved in the
325    reaction.</LI>   
326<LI>Improved probabilities and channels in the <TT>G4GEM</TT> model bring it
327    into closer agreement with data.</LI>
328<LI>Unit conversion errors were corrected in fission and Fermi break-up models.</LI>

343    G4EmLivermorePolarizedPhysics</TT>.</LI>
344<LI>New default builder for optical photon physics has been added:
345    <TT>G4OpticalPhysics</TT> together with its messenger,
346    <TT>G4OpticalPhysicsMessenger</TT>.</LI>
347<LI>All lists based on <TT>FTF</TT> and <TT>CHIPS</TT> modelling
348    use the improved versions of <TT>FTF</TT> and <TT>CHIPS</TT>.</LI>
349<LI>Newly added physics lists:
350    <UL>
351    <LI><TT>CHIPS</TT>, a physics-lists which uses the CHIPS model for  nuclear interactions of all energies and particles..</LI>
352    <LI><TT>QGSP_INCL_ABLA</TT>, a list using INCL/ABLA. It is mainly
353        intended for use with energies less than <TT>3 GeV</TT>. This is
354        useful for e.g. spallation studies and Accelerator Driven Systems (ADS)
355        applications.</LI>
356    </UL></LI>
357<LI>Other new physics-lists, already present in 9.3-Beta:
358    <UL>
359    <LI>Some are based on existing lists, with different transitions between
360        models:<BR>
361        <TT>FTFP_BERT_TRV</TT>, lower the transition energy from
362        BERTini to FTFP in the range from <TT>6-8 GeV</TT>.</LI>
363    <LI>Others  offer  options for EM physics:<BR>
364        <TT>FTFP_BERT_EMV, FTFP_BERT_EMX, QGSP_BERT_EMX, QGSP_BIC_EMY</TT>.</LI>
365    </UL></LI>
366<LI>Attempts to reduce usage of LEP in the intermediate energy range:
367    <UL>
368    <LI><TT>QGSP_BERT_NOLEP</TT>, using QGSP starting from <TT>8.5 GeV</TT>;</LI>
369    <LI><TT>QGSP_FTFP_BERT</TT>, using FTFP in the energy range between BERT
370        and QGSP.</LI>
371    </UL></LI>
372</UL>
373
374<B>Visualization, Graphical Representations & Interfaces</B>
375<UL>
376<LI>Improved ability of visualization system to render Boolean solids.
377    Certain cases involving very near co-planar faces used to result in
378    incorrect visualization (though not incorrect tracking).
379    An existing mechanism to deal with this has been improved; this mechanism
380    used to shift slightly the position of one solid in a chosen direction.
381    Now it attempts shifts in different directions by varying small amounts
382    until one is found that does not give an error. The system still can not
383    handle every situation. However it results in far fewer visualization
384    inaccuracies than were seen previously in such difficult cases.</LI>
385<LI>Visualization attributes can now be individually set for each volume within
386    a nested parameterization.</LI>
387<LI>Rich Trajectories and Rich Trajectory Points now include additional
388    information such as the complete volume path of the starting and ending
389    volume including all replica and copy numbers, etc.</LI>
390<LI>A new command, <TT>/vis/viewer/set/targetPoint</TT>, sets a specific point
391    to be the center of the view. Helps with doing extreme zoom in to a
392    specific point.</LI>
393<LI><B>gMocrenFile</B>: First Beta release of this new visualization driver to
394    output data in the <TT>gdd</TT> format used by the gMocren volume
395    visualization tool. <TT>gMocrenFile</TT> can include volume data from
396    sensitive detector volumes, or from command-based scoring meshes, in
397    addition to detector geometry and trajectories. Use new command
398    <TT>/vis/scene/add/psHits</TT> to add scorer hits to gMocren output.
399    For details, see the Application Developers Guide and the
400    <A HREF="http://geant4.kek.jp/gMocren/">gMocren web site</A>.</LI>
401<LI><TT>G4UIExecutive</TT>: a new utility class for automatic instantiation of
402    a user session selected according to defined environment variables
403    <TT>G4UI_USE_*</TT>.</LI> 
404<LI><B>Qt</B>: Continued improvements to this new driver. The <TT>Qt</TT>
405    visualization driver and the associated <TT>Qt</TT> User Interface now work
406    well on almost all platforms and with both Qt3 and Qt4 (but still considered
407    a Beta release due to a few rare combinations of commands on certain
408    platforms that can cause crashes).</LI>
409<LI>PostScript printing: vector and bitmapped printing through the UI command
410    <TT>/vis/ogl/printEPS</TT> is now fully functional for all OpenGL viewers
411    (previously only for OGLIX and OGLSX). Related new commands are
412    <TT>/vis/ogl/set/printSize</TT> and <TT>/vis/ogl/set/printFilename</TT>.</LI>
413<LI><B>HepRepFile</B>: new UI commands of the form <TT>/vis/heprep</TT> allow
414    easy control of output file name and output directory, whether a file name
415    should be reused (rather than having a sequential suffix appended at each
416    new file) and whether culled geometry volumes should be included.
417    Also fixed a bug in representation of <TT>G4Tubs</TT> which had caused
418    wrong visualization for cases in which the tube was at an unusual angle.</LI>

481<H2>6. Known Run-Time Problems and Limitations</H2>
482<UL>
483<LI>Reports have been made of particle tracks stuck at a volume boundary or at
484    an interface between volumes. This occurs infrequently, on the order of one
485    step per 10^11, but can effect large productions. The behaviour involved
486    particles which do not progress but move in very small steps, and as a
487    result the simulation of this track never finishes.
488    <UL>
489    <LI>A partial solution is implemented in this release, which uses an
490        existing mechanism to identify better these stuck tracks. It is able to
491        find all such tracks in the setups reported, using a large multiple of
492        the value of the geometrical tolerance for the setup. Users should pay
493        attention that the value is chosen well for their setup in case they
494        encounter a similar problem (using the existing functionality for
495        setting this value).</LI>
496    <LI>The treatment for these stuck tracks is to abandon the relevant track.
497        This results in the track being killed by the <TT>G4Transportation</TT>
498        process. A warning is issued (if compiled in verbose mode, the default)
499        in the case that the energy of the track is above a threshold energy.
500        Its default value is <TT>100 MeV</TT>. This value should be chosen by
501        a user in order to get warning for all particles of energy important to
502        your simulation. A new value can be assigned using the
503        <TT>SetThresholdWarningEnergy</TT> method of
504        <TT>G4Transportation</TT>.</LI>

519<H2>7. Compilation Warnings</H2>

521There may be a few compilation warnings on some platforms.
522We do not believe that any of these lead to incorrect run-time behaviour.

530<H2>8. Known Run-Time Warnings</H2>
531
532The following message may be written to standard output at the end of a program:
533<PRE>
534    G4Transportation: Statistics for looping particles
535       Sum of energy of loopers killed:
536       Max energy of loopers killed:
537</PRE>
538It provides the total energy (in <TT>MeV</TT>) of tracks  killed due to
539excessive number of steps ('looping') during the simulation, and the maximum
540energy of such a track. Such behaviour can be due to looping in magnetic fields
541or being abandoned due to being stuck at geometrical boundaries, as mentioned
542in <A href="#6.">Section 6</A>.
543<P></P>
544In case either of these reported energies is significant, we recommend
545increasing the verbosity of <TT>G4Transportation</TT> to obtain information for
546each track killed. A user can change the threshold energy above which particles
547are killed more reluctantly (only after significant additional effort) using
548the method <TT>SetThresholdImportantEnergy</TT> of <TT>G4Transportation</TT>.
549The default value is <TT>250 MeV</TT>.

945<UL>
946    <LI>Introducing <TT>G4SmartTrackStack</TT> class. By using this new stack
947        as the urgent stack of <TT>G4StackManager</TT>, the next track popped
948        up from the stack is not necessarily the last track stored in the
949        stack, but the track of same particle type as the previous one, as
950        long as such a track exists in the urgent stack. This mechanism is
951        expected to improve the performance for ultra-large scale simulation
952        such as LHC, by increasing the cache hit rate of the physics tables.<BR>
953        The use of <TT>G4SmartTrackStack</TT> is temporarily optional. To use
954        it, one should uncomment the <TT>#define</TT> line in
955        <TT>include/evmandefs.hh</TT>.</LI>
956    <LI>Added UI comand <TT>/event/stack/verbose</TT> providing a short report

970        Measured a factor 2 to 3 improvement in initialisation speed when
971        building physics tables.
972        Modified <TT>BuildRangeVector()</TT> where integration is perfomed
973        in this method; extended for <TT>e+/e-</TT>.
974        Changed <TT>TotBin</TT> to be constant (i.e. same for all converters)
975        and set to 100 (200 for previous versions).
976        Added <TT>MaxEnergyCut</TT> (<TT>10 GeV</TT> set in default).
977        Added <TT>fRangeVectorStore</TT> to ensure that range-vector is
978        created only once for each material. Do not apply converter for neutron,
979        anti-proton, and anti-neutron.</LI>
980    <LI>A new method <TT>ResetConverters()</TT> has been added to
981        <TT>G4ProductionCutTable</TT>. This method allows to reduce the memory
982        footprint by clearing temporary loss tables and range vectors used at
983        initialization, if invoked when starting the first run of a session.</LI>
984    <LI>Added possibility to handle cuts for protons.</LI>

1182<LI>Improved ability of visualization system to render Boolean solids.
1183    Certain cases involving very near co-planar faces had resulted in incorrect
1184    visualization (though not incorrect tracking). A previously included
1185    mechanism to deal with this by shifting the position of one solid in a
1186    chosen direction has been expanded by attempting shifts in different
1187    directions by varying small amounts until one is found that does not give
1188    an error. The system still can not handle every situation, but results in
1189    far fewer visualization inaccuracies than were previously seen in such

1514<LI>ICRU'73 stopping power classes:
1515    <UL>
1516    <LI>Migrated to the <TT>G4VIonDEDXTable</TT> interface: access methods
1517        of physics vectors have changed (vectors can also be identified via
1518        atomic number of material if material is pure). Classes now deliver
1519        mass stopping powers instead of stopping powers per unit length.
1520        Any dependency on ICRU'73 material densities was removed (no densities
1521        are included in the classes any longer). Stopping power vectors are
1522        now only built on request and not anymore in the constructor.
1523        Affected classes: <TT>G4IronStoppingICRU73, G4MaterialStoppingICRU73</TT>
1524        and <TT>G4SimpleMaterialStoppingICRU73</TT>.</LI>
1525    <LI><TT>G4IronStoppingICRU73</TT>: extended upper limit of the data vector
1526        from <TT>10 MeV</TT> to <TT>1 GeV</TT>; 53 bins are now used.
1527        Added <TT>G4WATER</TT> data. Also fixed <TT>GetDEDX()</TT> methods in
1528        these classes for <TT>E=10 MeV</TT> (upper limit).</LI>
1529    <LI><TT>G4MaterialStoppingICRU73</TT>: extended energy range of revised
1530        ICRU'73 tables for water from <TT>0.025-10 MeV/u</TT> to
1531        <TT>0.025-1 GeV/u</TT>.
1532        Added new function <TT>AddPhysicsVectorFullRange()</TT> for creating
1533        corresponding physics vectors. Changed material name from
1534        <TT>G4_NYLON-6/6</TT> to <TT>G4_NYLON-6-6</TT>.</LI>
1535    </UL></LI>
1536<LI>New class <TT>G4IonStoppingData</TT>, which can read ion stopping power
1537    vectors contained in <TT>G4LEDATA</TT> data set; allows for inclusion of
1538    larger physics vectors than those in the ICRU'73 classes, where vectors
1539    are restricted to the maximum energy <TT>10 MeV/nuc</TT>.</LI>
1540<LI><TT>G4NistMaterialBuilder</TT>: mean ionisation potential for <TT>G4_WATER</TT>
1541    is set to <TT>78 eV</TT> according to GSI Annual Report (2008) p.373, in
1542    order to be consistent with ICRU'73 tables. Fixed ICRU'73 data provided by
1543    Prof. P.Sigmund (Univ. Southern Denmark): <TT>G4WATER, G4WATER_VAPOR,
1544    G4_NYLON-6-6</TT> (in <TT>G4MaterialStoppingICRU73</TT>); <TT>G4_Cu</TT>
1545    (in <TT>G4SimpleMaterialStoppingICRU73</TT>).
1546    Changed material names, <TT>G4_NYLON-6/6</TT> to <TT>G4_NYLON-6-6</TT>,
1547    and <TT>G4_NYLON-6/10</TT> to <TT>G4_NYLON-6-10</TT>, to allow matching
1548    with ion stopping power data files. Old names can still be used for
1549    backward compatibility. Changed density of <TT>G4_GRAPHITE</TT> according
1550    to PDG-2008, added new material <TT>G4_GRAPHITE_POROUS</TT>.</LI>
1551<LI><TT>G4NistMessenger</TT>: added UI command to print parameters of density
1552    effect data. Improved implementation of UI commands in

1555<LI><TT>G4VIonDEDXTable</TT>: added interface class for electronic stopping
1556    power tables for ions. Added new method <TT>BuildPhysicsVector()</TT>
1557    which invokes the build of physics vectors on demand in the initialisation
1558    phase. Added method <TT>BuildPhysicsVector()</TT> according to base class
1559    for <TT>G4ExtDEDXTable, G4SimpleMaterialStoppingICRU73,
1560    G4MaterialStoppingICRU73</TT> and <TT>G4IronStoppingICRU73</TT>.</LI>
1561<LI><TT>G4ExtDEDXTable</TT>: new utility class to handle external
1562    electronic stopping power tables for ions.</LI>
1563<LI>Use 'const' references for strings as arguments/return-values in material
1564    properties tables and related classes. Inlined some methods and some minor
1565    cleanup.</LI>
1566<LI>Added <TT>Entries()</TT> method to <TT>G4MaterialPropertyVector</TT> and
1567    accessors for maps in <TT>G4MaterialPropertiesTable</TT>, required for
1568    internal use in persistency of material properties. Make visible
1569    <TT>GetEntry()</TT> accessor in <TT>G4MaterialPropertyVector</TT> for
1570    use restricted to persistency.</LI>
1571<LI>Increased flexibily of G4SurfaceProperty and G4OpticalSurface classes
1572    to allow for lookup-table boundary process simulations.</LI>
1573<LI><TT>G4Element</TT>: added method <TT>GetNbOfShellElectrons()</TT>
1574    returning the number of electrons on a shell.</LI>
