            <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>
            Best regards,<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>
