Dear Users,
I use the Proton beam and PMMA target. I want to get the source locations
of the Prompt gammas and details of secondary particles created inside the
target with event number.
How I can get the source locations of the prompt gammas inside the target?
I usually put a PET scanner connected with Sensitive detector, get the
events detail coning inside the Pet detector but now I need the locations
of the prompt gammas inside the target?
I want to track the positions and time of all steps,tracks starting from
the phantom to detector.(Primary Proton to secondaries).
What I did, I used the sensitive detector on the phantom and crystal both
and sued simple scanner system. But it seems to me that the only get
information about the phantom SD. My goal is to get the phase space data of
the prompt gamma detector and map them on the detector.
Regards
Atiq
