[Gate-users] C11 ion source

[Mahdjoub Hamdi]

Hy,

 

  We 're simulating C11 ion source for PET applications, the simulation run
without error  but the obtained ROOT file is empty, we tried with the back
to back and the positron source and that's  worked correctly .

 

We 've tried  to fix it following all the answers of  this question posted
in the mailing list about one years old,  but no solution has solved this
problem, this is  our macro for the physics and the ion  source:

Or, It seems like our GATE installation is missing some files  (Gate v6.1

Thank you in advance and any information greatly appreciated,

 

Kind regards
