I'd like to generate cherenkov photons as primaries to study the detector response (DIRC).
I tryied to use FairBoxGenerator for this purpose (generate particles with PDG = 5000050), but the simulation crashes at generation stage (see errors below).

Dose anybody know any ways to generate cherenkov photons with given properties originating from, say (49., 11., 0.)cm ??


There was a crash (kSigFloatingException).
