Dear Experts,
Thank you Ricardo for the reply. I see a non-zero value as you point out.
However, I start the beam in vacuum and try to count them as soon as they
pass the boundary material. I could probably be missing a very simple point
that I cannot figure out. Please forgive my ignorance but I think I should
expect to see the number of beam particles (100 000, due to no interaction
in vacuum?). Am I not correct? Also it only takes a couple of seconds to
say 'Finished OK' without any progress (no green bar appears). Shouldn't
the program run for a while?
Thank you for any further help in advance,
Mehmet
