[fluka-discuss]: Re: fast and slow component in a scintillator

Dear Anton,
ok, this way looks fine, I'll try that.
Just another question. Is there a way to set the ratio between the fast component and the slow one for each type of particle (N.B.: this ratio is fixed for each type of type of particle, i.e. for electrons, protons, neutrons etc.)?
In fact, what I need to do in my simulation is to distinguish the particles produced in hadronic and electromagnetic showers via this ratio.
So, from a "theoretical" point of view, I have to set in Fluka the (known) values of these ratios. But practically, how to do that? I can't see any card of interest for my purpose.
Hope you'll understand what I mean.

Dear Alessia,

One can implement different time constants for different scintillation photon emission energies via the OPT-PROD card (see WHAT(3) for SDUM=SCINTILL or SCINT-WV or SCINT-OM). You have to issue one card per emission line (max. 3 possible). Note that the age of optical photons is accessible via the AGOPPH variable (OPPHST common).

I hope this answers your question.

Cheers, Anton

Subject: [fluka-discuss]: fast and slow component in a scintillator

Hi everybody,
I have to simulate the scintillation process generated by electrons (or other charged particles, doesn't matter) on Barium Fluoride.
This kind of material has two different components in the time of emission: one fast at 0.6 ns and one slow at 630 ns. I was wondering if it is possible to implement these two components in Fluka (I've taken a look at several examples but no one treats the scintillation in this way).

Thank you in advance
