[Gate-users] A problem with GATE V6.1 X-ray spectrum calculation

[Zhihuaigu]

Dear Gate users,

I am trying to use electrons to hit the tungsten target to produce X-rays. But 
the electrons only scatter at the target. Bremsstrahlung process were not found 
and no photons were emitted. Did anyone have simulate the similar process and 
know where is the problem. 


the relevent script language in physics.mac is list at below:

/gate/physics/addProcess ElectronIonisation
/gate/physics/processes/ElectronIonisation/setModel StandardModel e-
/gate/physics/addProcess Bremsstrahlung
/gate/physics/processes/Bremsstrahlung/setModel StandardModel e-

10000events were run.

Thank you very much for your help.
Best regards,
