    9897- GEANT4 SIMULATION OF THE NEW CENBG MICRO AND NANO PROBES FACILITY
     
    124123
    125124
    126 ---->3. SET-UP
    127                                                                        
    128 - a standard Geant4 example GNUmakefile is provided                     
     125------->3 VISUALIZATION
    129126
    130 The following section gives the necessary environment variables.                     
    131 
    132 ------->>3.1  ENVIRONMENT VARIABLES
    133 
    134 All variables are defined with their default value.
    135 
    136  - G4SYSTEM = Linux-g++
    137 
    138  - G4INSTALL              points to the installation directory of GEANT4;
    139 
    140  - G4LIB                  point to the compiled libraries of GEANT4;
    141 
    142  - G4WORKDIR              points to the work directory;
    143 
    144  - CLHEP_BASE_DIR         points to the installation directory of CHLEP;
    145 
    146  - G4LEDATA               points to the low energy electromagnetic libraries;
    147 
    148  - LD_LIBRARY_PATH = $CLHEP_BASE_DIR/lib
    149 
    150  - G4LEVELGAMMADATA       points to the photoevaporation library;
    151 
    152  - NeutronHPCrossSections points to the neutron data files;
    153 
    154  - G4RADIOACTIVEDATA      points to the libraries for radio-active decay
    155                           hadronic processes;
    156  
    157 However, the $G4LEVELGAMMADATA, $NeutronHPCrossSections and $G4RADIOACTIVEDATA
    158 variables do not need to be defined for this example.
    159 
    160 Once these variables have been set, simply type gmake to compile the Microbeam
    161 example.
    162 
    163 ------->>3.2  VISUALIZATION
    164 
    165 The user can visualize the targeted cell with OpenGL, DAWN and vrml,
    166 as chosen in the microbeam.mac file. OpenGL is the default viewer. The
    167 cytoplasm in shown in red and the nucleus in green.
    168 
     127The user can visualize the targeted cell by uncommenting the following line in
     128microbeam.mac:
     129#/control/execute vis.mac
    169130
    170131---->4. HOW TO RUN THE EXAMPLE                                         
    171132
    172 In interactive mode, run:
     133The variable G4ANALYSIS_USE must be set to 1.
    173134
    174 > $G4WORDIR/bin/Linux-g++/Microbeam
     135In order to generate histograms, at least one of the AIDA implementations should be
     136 available.
     137 
     138The code should be compiled with gmake and run with :
    175139
    176 The macro microbeam.mac is executed by default.
    177 All visualisation commands are in the vis.mac macro file.
     140> $G4WORDIR/bin/$G4SYSTEM/Microbeam
     141
     142The macro file microbeam.mac is read by default.

    185150---->6. SIMULATION OUTPUT AND RESULT ANALYZIS                                   
    186151
    187 This example does not need any external analysis package.
    188 The output results consists in several .txt files:
     152The output results consist in several a microbeam.root file, containing several
     153ntuples:
    189154
    190 * dose.txt : gives the total deposited dose in the cell nucleus and in the cell
     155* total deposited dose in the cell nucleus and in the cell
    191156cytoplasm by each incident alpha particle;
    192157
    193 * 3DDose.txt : gives the average on the whole run of the dose deposited per
     158* average on the whole run of the dose deposited per
    194159Voxel per incident alpha particle;
    195160
    196 * range.txt : indicates the final stopping (x,y,z) position of the incident
     161* final stopping (x,y,z) position of the incident
    197162alpha particle within the irradiated medium (cell or culture medium)
    198163
    199 * stoppingPower.txt : gives the actual stopping power dE/dx of the incident
     164* stopping power dE/dx of the incident
    200165alpha particle just before penetrating into the targeted cell;
    201166
    202 * beamPosition.txt : gives the beam transverse position distribution(X and Y)
     167* beam transverse position distribution(X and Y)
    203168just before penetrating into the targeted cell;
    204169
    205 These files can be easily analyzed using for example the provided ROOT macro
     170These results can be easily analyzed using for example the provided ROOT macro
    206171file plot.C; to do so :
    207172* be sure to have ROOT installed on your machine
     
    210175* under your ROOT session, type in : .X plot.C to execute the macro file
    211176
    212 A graphical output obtained with this macro for 40000 incident alpha particles
    213 is shown in the file microbeam.gif
    214 
    215 The simulation predicts that 95% of the incident alpha particles detected by the
    216 gas detector are located within a circle of 10 um in diameter on the target, in
    217 nice agreement with experimental measurements performed on the CENBG setup.
