Hi,

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 ??


Thanks.
