Hi Nick. Thanks for your replay. It helped me much.

One question remains obscure for me.
1) How can one calculate WHAT(2) "fraction of deposited energy going
into i-th scin. photon emission" parameter?
2) Should it be specified in scintillator material parameters or it
can be calculated indirectly from other parameters too, for example
luminosity and emission peak wavelength?

I supposed formula Luminosity[ph/ev]*Energy(peak emission)[ev], am I right?

(I converted luminosity from [ph/Mev] to [ph/ev])

 The USRBDX card for OPTIPHO needs to have the binning range set
 to appropriate energies.

 This should read "You want to set an OPT-PROP ...". From this
 card you need to set _at least_ the absorption coefficient and
 the material you're assigning the properties to (ie. YAG). 
 Setting diffusion coefficients will increase the time per
 particle. 
 
 Attached is your last INP file modified to work.  I include
 comments on cards I've changed.

 I did corrections that you mention and was able to get
 nice USRBDX

 zeroes.....(: 
 I am attaching new corrected input file. 
 
 As I understood from your explanation card OPT-PROP (sdum

 I am little confused about WHAT(2) ( "fraction") parameter
 of OPT-PROD(

        Here are the issues with your input: 
         
        1) your source is at 20 MeV, and is
 isotropic.&nbsp; If you test it 
 <div class="im">       with a beam, make sure its in the
 positive direction, and set the 
        primaries lower as the processing time is ~2 hrs on
 an i7 if it's 
 </div>
        made directional with your current
 settings.&nbsp; Using the SENSITIV 
 <div class="im">       sdum on OPT-PROP you can probably
 lower the OPT-PHOT production 
        (and reduce CPU load) if you are trying to make
 other measurements 
 </div>
        at the same time in your simulation. 
         
 <div class="im">       2) when entering in the wavelengths
 for the OPT-PROP (sdum 
        WV-LIMITS) cards you want them in cm, they were all
 entered in as 
 </div>
        meters, you technically don't need them to run the
 simulation 
         
 <div class="im">       3) same issue with OPT-PROD (sdum
 SCINT-WV), it was also in 
 </div>
        meters.&nbsp; This card is very much needed.
 
         
 <div class="im">       4) you explained you want an electron
 beam. But you have the 
 </div>
        source card set to isotropic at 20 MeV. :-) 
         
 <div class="im">       5) You need to set an appropriate
 upper and lower energy in the 
 </div>
        USRBDX card for binning the optical
 wavelengths.&nbsp; I usually use 
        1E-9 to 1E-8 initially. 
         
 <div class="im">       6) You may want to set an OPT-PROP
 (sdum blank) card to set an 
        index of refraction, absorption and diffusion
 coefficients. This 
 </div>
        will increase the processing time per particle
 however. 
         
        Hope this helps.
