    3636 2- PHYSICS LIST
     37 
     38 Physics lists can be local (eg. in this example) or from G4 kernel
     39 physics_lists subdirectory.
     40     
     41 Local physics lists:   
     42 - "local"      standard EM physics with current 'best' options setting.
     43                these options are explicited in PhysListEmStandard             
     44 - "standardSS" standard EM physics with single Coulomb scattering
     45                instead of multiple scattering;
     46 - "standardNR" standard EM physics with single Coulomb scattering
     47                process G4ScreenedNuclearRecoil instead of the
     48                multiple scattering for ions with energy less than
     49                100 MeV/nucleon; the new process was developed
     50                by M.H. Mendenhall and R.A. Weller from Vanderbuilt
     51                University and published in NIM B 277 (2005) 420.
     52                In later Geant4 releases the process will be a part
     53                of Geant4 source, currently it is released together
     54                with its mathematical tool c2_functions in current
    3755
    38     The following EM physics lists are available in this example:       
    39     - "standard"     standard EM physics (default)
    40     - "livermore"    low-energy EM physics using Livermore data
    41     - "penelope"     low-energy EM physics implementing Penelope models
    42     - "standardSS"   standard EM physics with single Coulomb scattering
    43                      instead of multiple scattering; G4ionIonisation is
    44                      substituted by G4ionGasIonisation for GenericIons
    45     - "standardNR"   standard EM physics with single Coulomb scattering
    46                      process G4ScreenedNuclearRecoil instead of the
    47                      multiple scattering; the new process was developed
    48                      by M.H. Mendenhall and R.A. Weller from Vanderbuilt
    49                      University and published in NIM B 277 (2005) 420.
    50                      In later Geant4 releases the process will be a part
    51                      of Geant4 source, currently it is released together
    52                      with its mathematical tool c2_functions in current
    53                      example
    5456   
    55     Alternatively, the user may use predefined Geant4 builders:
    56     - "emstandard"        G4EmStandardPhysics builder
    57     - "emstandard_opt1"   G4EmStandardPhysics_option1 builder
    58     - "emstandard_opt2"   G4EmStandardPhysics_option2 builder
    59     See geant4/source/physics_lists/History for details       
    60 
    61     Optional components can be added:
    62     - "elastic"       elastic scattering of hadrons
    63     - "HElastic"
    64     - "QElastic"   
    65     - "binary"        QBBC configuration of hadron inelastic models
    66     - "binary_ion"    Binary ion inelastic models               
     57 From geant4/source/physics_lists/builders:     
     58 - "emstandard_opt0" recommended standard EM physics for LHC
     59 - "emstandard_opt1" best CPU performance standard physics for LHC
     60 - "emstandard_opt2"     
     61 - "emstandard_opt3" best current advanced EM options.
     62                     analog to "local" above 
     63 - "emlivermore"  low-energy EM physics using Livermore data
     64 - "empenelope"   low-energy EM physics implementing Penelope models
     65

     69 - "QElastic"   
     70 - "binary"        QBBC configuration of hadron inelastic models
     71 - "binary_ion"    Binary ion inelastic models
     72                       
     73 Physics lists and options can be (re)set with UI commands
     74   
     75 Please, notice that options set through G4EmProcessOPtions are global, eg
     76 for all particle types. In G4 builders, it is shown how to set options per
     77 particle type.

    121137     (command /testem/stepMax )
    122138 
    123      The result is a 1D histogram  which is the total energy deposited along
    124      the trajectory of the incident particle.
    125      
    126      The histogram is saved in hbook format (testem7.hbook)
     139     The result is a 1D histogram, which is the total energy deposited
     140     along the trajectory of the incident particle.

    130144     The total energy deposited is plotted in MeV/mm per incident particle. 
    131145
    132      Note that, by default, histograms are disabled. To activate them, uncomment
    133      G4ANALYSIS_USE in GNUmakefile.
    134      
    135   7- DOSE IN 'TEST-VOLUMES'
     146     The next histogram alowing to have a zoom around the Bragg peak. Its binning
     147     should be defined via UI command:
     148     /testem/histo/setHisto 1 nbins xmin xmax
     149
     150     The last histogram shows the projectile range. Its binning should be defined
     151     similary by the UI command:
     152     /testem/histo/setHisto 2 nbins xmin xmax
     153     
     154  8- USING HISTOGRAMS
     155
     156     By default the histograms are not activated. To activate histograms
     157     the environment variable G4ANALYSIS_USE should be defined. For instance
     158     uncomment the flag G4ANALYSIS_USE in GNUmakefile.
    136159 
    137      The energy deposited in the test-volumes (tallies) defined in
    138      DetectorConstruction are printed at EndOfRun, both in MeV and gray.
    139  
     160     To use histograms, at least one of the AIDA implementations should be
     161     available. See InstallAida.txt
    140162
    141  8- USING HISTOGRAMS
    142 
    143   By default the histograms are not activated. To activate histograms
    144   the environment variable G4ANALYSIS_USE should be defined. For instance
    145   uncomment the flag G4ANALYSIS_USE in GNUmakefile.
    146 
    147   It is possible to choose the format of the histogram file (hbook, root, XML):
    148   comment/uncomment 1 line in  RunAction::bookHisto().
    149  
    150   Before compilation of the example it is optimal to clean up old files:
     163     Before compilation of the example it is optimal to clean up old files:
    151164        gmake histclean
    152165        gmake
    153166
    154   To use histograms, at least one of the AIDA implementations should be
    155   available (see http://aida.freehep.org).
    156  
    157  8a - PI
     167     It is possible to choose the format of the histogram file (hbook, root, XML):
     168     /testem/histo/setHistoType root
    158169
    159   A package including AIDA and extended interfaces also using Python is PI,
    160   available from: http://cern.ch/pi
    161 
    162   Once installed PI or PI-Lite in a specified local area $MYPY, it is required
    163   to add the installation path to $PATH, i.e. for example, for release 1.2.1 of
    164   PI:
    165   setenv PATH ${PATH}:$MYPI/1.2.1/app/releases/PI/PI_1_2_1/rh73_gcc32/bin
    166 
    167   CERN users can use the PATH to the LCG area on AFS.
    168   Before running the example the command should be issued:
    169   eval `aida-config --runtime csh`
    170 
    171  8b -  OpenScientist
    172 
    173   OpenScientist is available at http://OpenScientist.lal.in2p3.fr.
    174 
    175   You have to "setup" the OpenScientist AIDA implementation before compiling
    176   (then with G4ANALYSIS_USE set) and running your Geant4 application.
    177 
    178  On UNIX you setup, with a csh flavoured shell :
    179         csh> source <<OpenScientist install path>/aida-setup.csh
    180         or with a sh flavoured shell :
    181         sh> . <<OpenScientist install path>/aida-setup.sh
    182  On Windows :
    183         DOS> call <<OpenScientist install path>/aida-setup.bat
    184 
    185   You can use various file formats for writing (AIDA-XML, hbook, root).
    186   These formats are readable by the Lab onx interactive program
    187   or the OpenPAW application. See the web pages.
    188 
    189 
    190   With OpenPAW, on a run.hbook file, one can view the histograms
    191   with something like :
    192         OS> opaw
    193         opaw> h/file 1 run.hbook  ( or opaw> h/file 1 run.aida or run.root) 
    194         opaw> zone 2 2
    195         opaw> h/plot 1
    196         opaw> h/plot 2
     170     The default name "testem7" can be changed:
     171     /testem/histo/setHistoName myname
