Question fKillTrackAndSecondaries Background Process 

Forum: Event and Track Management
Date: 27 Jun, 2018
From: <fran>

Dear all,

can anyone explain what exactly happens when setting the track status in UserSteppingAction to fKillTrackAndSecondaries? More specifically, imagine a gamma passing a collimator slit (Wolfram) and interacting via compton scattering in a water phantom located right after the collimator. Imagine the case of a large scattering angle causing the gamma to be backscattered to the collimator and interacting with wolfram. In my scenario I would like to exclude any collimator scattering effects, so if track->GetMaterial()->GetName() is equal to "Wolfram", I call track->SetTrackStatus(fKillTrackAndSecondaries); However, in my simulations I get an unrealistic intensity drop when excluding collimator scattering. Is fKillTrackAndSecondaries killing all secondary particles currently in the stack (so in my example the secondary electron from compton scattering in water as well) or just the secondary particles produced in the step where gamma is interacting with Wolfram?

I would be very grateful for any hints, thank you in advance!

Best regards, Fran
