Hello @anum.asif,
Quickly checking your attached Flair file I notice two things:
- I believe in your BEAM card you define a 0 GeV/c momentum electron beam instead of 9 MeV kinetic energy. The value will be overwritten to the 200 GeV/c default.
- For this reason you also don’t see any results at your first boundary USRBDX scoring: Since you defined as going up to a maximum energy of 9 MeV of course it will be far out of range. Using your defined settings, you will however get some secondary particles which is what you get from the exiting boundary USRBDX.
Do you get expected results when you make these changes?
Best regards, hope this helps,
Andreas
