[Gate-users] A problem with Gate spectrum calculation

[Zhihuaigu]

Dear Gate colleagues,

i have a problem with Gate x-ray spectrum calculation. when electrons were 
emitted to hit the tungsten target, no photons were found. 10000 events were 
run.
 
The relevant script language in physics.mac is listed below:
_______________________________________________________________________________
/gate/physics/addProcess ElectronIonisation
/gate/physics/processes/ElectronIonisation/setModel StandardModel e-
 
/gate/physics/addProcess Bremsstrahlung
/gate/physics/processes/Bremsstrahlung/setModel StandardModel e-
 
There must be something wrong. Can you do me a favor and explain it for me? I 
will really appreciate. Thank you very much for reading my letter.
 
Regards,
