Dear Tanin,
you need to lower both the production and transport thresholds for
e+/e- and gammas to have an energy deposition in your detector.
You have PRECISION defaults (which sets these thresholds to 100 keV),
but your source emits 15 keV photons: this is why you get zero.
I send you a modified input file in which I have added two EMFCUT
cards to put the thresholds to 1 keV. Give it a try: you should be
able to score correctly now.
Kind regards,
Andrea
