Hi Boram,
I think you can consider using kill actor inside detector or just before detector to exclude other particles.

Dear Gate users

I am testing for gamma and neutron detection using 20 cm x 20 cm detector and attachCrystalSD. Other actors can set the type of particle for detection.
However, I can't find a setting that only neutron detects in the digitizer. Can you help me how to count only neutrons?



Thank you :)

I have a simulation where i can use a Proton Beam to radiate a Phantom. I want to reconstruct an Image of the Positron emission distribution produced by inelastic proton interactions. What I want to check is like In-Beam PET.
Can someone help me how to proceed?
(1)  I have the PET model of my detector.
(2) I have the simulation which can generate the phase space data of the Positrons generated by the Protons.
My goal is to reconstruct the Image of the Positron distribution along the width of the phantom using PET for the range verification.
My Problem is to how to save the positron distribution and then to use it in PET application.
Can you please guide me to proceed? Thanks!
Regards
Atiq
