[Gate-users] GPS Bremsstrahlung spectra

[Nada Fakhoury]

Dear all,

I am quite new at using Gate, so I have many questions, but I will  
trouble you today with just the one.

I am trying to simulate a Linac beam, so as a first step I am trying  
to approach it with the gps commands.
So I am wondering, does Gate support the bremsstrahlung command?

I tried defining it as

/gate/source/mybeam/gps/particle gamma
/gate/source/mybeam/gps/ene/type Brem
/gate/source/mybeam/gps/ene/min 1 eV
/gate/source/mybeam/gps/ene/max 6 MeV

for starters, but I am getting a repeated error saying

*****EXPMIN=0. Choose different E's or Temp
*****EXPMAX=0. Choose different E's or Temp


I tried defining my source as done in the examples and the RT  
benchmark, but I get a dose distribution that seems way off... (

Thank you in advance,

Nada.
