hi,
I recently simulate 6 MV Elekta Precise Linac photon beam for radiotherapy by Gate , I am not sure to properly build the physics process which I just set photon and electron Standard EM Physics list as the recommend on website http://www.opengatecollaboration.org/sites/opengatecollaboration.org/files/Physics_List_for_Radiation_Therapy_applications.pdf.
I set the electron source character as following :
/gate/source/addSource mybeam gps
/gate/source/mybeam/gps/particle e-
/gate/source/mybeam/gps/pos/type Beam
/gate/source/mybeam/gps/pos/rot1 0 1 0
/gate/source/mybeam/gps/pos/rot2 1 0 0
/gate/source/mybeam/gps/pos/shape Circle
/gate/source/mybeam/gps/pos/centre 0. 0. 0.6 mm
/gate/source/mybeam/gps/pos/sigma_x 3 mm
/gate/source/mybeam/gps/pos/sigma_y 3 mm
/gate/source/mybeam/gps/ang/rot1 1 0 0
/gate/source/mybeam/gps/ang/rot2 0 1 0
/gate/source/mybeam/gps/ang/type beam1d
/gate/source/mybeam/gps/ang/sigma_r 0 deg
/gate/source/mybeam/gps/ene/type Gauss
/gate/source/mybeam/gps/ene/mono 5.8 MeV
/gate/source/mybeam/gps/ene/sigma 0.074 MeV
/gate/source/mybeam/gps/direction 0 0 -1
and EM Physics list:
gamma: G4PhotoElectric
G4ComptonScattering
G4GammaConversion
G4RayleighScattering
e- and e+: G4eMultipleScattering, G4eIonisation, G4eBremsstrahlung,G4eplusAnnihilation.
ElectroMagnetic option Value
Min Energy 100 eV default
Max Energy 10 TeV default
dE/dx table binning 220 default = 84
Lambda table binning 220 default = 84
Are these parameters proper for simulating 6 MV Elekta Precise Linac photon beam for radiotherapy by Gate?
Best Wishes,
Bin
