Dear Roesler,
Thanks for your reply. Sorry for my ambiguous description.
In my original simulation, I used a source subroutine to get primary muons.
For a simple case, I supposed a muon beam with energy 100GeV just at +z
direction (0,0,1000) shoot into the lab(the direction is -z), and the
detector is at center of geometry. I wish if a muon go through all of the
three fold layers(region RT, RM, and RB), the MuonTracker would record its
muon id (NCASE). But I don't know how to do this, I initially recorded the
informations occured in any three fold layer and liquid scinllator. It seems
like every muon will be recorded in all three fold layers and liquid
scintillator, but I only got the informations occured in liquid scinllator.
There is no interaction between muon and three fold layers. I don't know if
my configurations of geometry or others are wrong. Or better way can achieve
this purpose. Thank you very much.
Attached is correct files. In the mgdraw.f file, the code which is used to
take data of muon is labeled "**** Record the Muon information in specific
region Start ****". Thank you very much!
Best regards,
Yung-Shun
