<div>we also experiencing similar issue, there is definitely a

gate-users,<br>
<br>
<br>
I try to simulate a Bragg curve from carbon beam with energy
of 270 MeV per nucleon.<br>
My setting for the beam are:<br>
<br>
/gate/source/addSource Carb12 gps<br>
<br>
/gate/source/Carb12/gps/particle ion<br>
/gate/source/Carb12/gps/ion 6 12 6 0 # zeros<br>
#/gate/source/Carb12/gps/ion 6 11 6 0 # valid data<br>
/gate/source/Carb12/gps/pos/type Beam<br>
/gate/source/Carb12/gps/pos/rot1 0 1 0<br>
/gate/source/Carb12/gps/pos/rot2 1 0 0<br>
/gate/source/Carb12/gps/pos/shape Circle<br>
/gate/source/Carb12/gps/pos/centre 0 0 0 mm<br>
/gate/source/Carb12/gps/pos/sigma_x 2 mm<br>
/gate/source/Carb12/gps/pos/sigma_y 2 mm<br>
/gate/source/Carb12/gps/ene/mono 3240 MeV # 270 MeV per
nucleon<br>
/gate/source/Carb12/gps/ene/type Mono<br>
/gate/source/Carb12/gps/direction 0 0 1<br>
<br>
The problem that DoseActor file contains only zeros, but
when i change ion type from carbon 12 to carbon 11
"/gate/source/Carb12/gps/ion 6 11 6 0" the dose distribution
data for the Bragg curve becomes correct. What is the proper
way for carbon 12 beam?<br>
<br>
<br>

Dear David,<br>
<br>
I've tried different physics lists: emstandard_opt3, QGSP_BERT_EMV,
<a
href="http://www.opengatecollaboration.org/sites/opengatecollaboration.org/files/Physics_List_for_Carbontherapy_applications.pdf">physics
list for application with carbon beam</a>.<br>
GATE 7.0 works fine with proton and C11, i didn't tested it in
previous versions though.<br>
<br>
Best regards.<br>
