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.

129<B>Run</B>
130<P> </P>
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>

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>

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>

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>

193<B>Visualization</B>
194<P> </P>
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>

223<H2>4. New Developments and Capabilities </H2>
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>

241
242<B>Detector description persistency</B>
243<UL>
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>
248</UL>
249
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>

276<LI>Data set: G4EMLOW version 6.9 is required.</LI>
277</UL>
278
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:

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.

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>.

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>

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.

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

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
1553 <TT>G4NistManager</TT>, G4NistMessenger</TT> and

1555<LI><TT>G4VIonDEDXTable</TT>: added interface class for electronic stopping
1556 power tables for ions. Added new method <TT>BuildPhysicsVector()</TT>
