    Dear Gunasingha,
    optical photons are not automatically generated by FLUKA!
    Parameters about generation have to be put by the users by means of
    datacards and (if needed) specific users routines.
    Please have a careful study of Chapter 13 of the FLUKA manual and
    of all the commands there described.

Through the mgdraw.f routine I can see the electron was created after muon decay. But I don't see any hits on PMTs due to the optical photons from electron. I need to get the hit time and hits due to electron.
