Optical photons

hi friends
I want to know that what is fraction in opt-prod card for transport opticalphotons?

Dear Hajar,

the meaning of fraction is: fraction of deposited energy going into i^th scintillation photon emission.

For more information see Chapter 12 of the manual: 12} Generating and propagating optical photons | FLUKA

Cheers,
David

dear david
i dont know how to calculate fraction of deposited energy going into i^th scintillation photon emission for example when scintillation yield is 900photon/MeV. i study the manual but not understand. thanks

Dear Hajar,

to calculate the fraction for a given yield, you need to multiply the yield (900 photon/MeV in this case) with the energy of the optical photon you want to simulate, then divide it with 1 MeV.

Cheers,
David
