Question Extending the electromagnetic energy processes' upper limit 

Forum: Physics List
Date: 01 Mar, 2011
From: Tomasz Sakrejda <Tomasz Sakrejda>

Hello,

I'm working on simulating utlra-high-energy cosmic rays and I've been trying to extend the physics processes beyond their 100 TeV limits. I believe that I've accomplished this properly for the hadronic processes- (I did so by editing the lists and builders in geant4/source/physics_lists/ and recompiling the libraries), but fixing the electromagnetic portion eludes me. In the program output, there is a section where the processes are listed, in the format:
phot:   for  gamma    SubType= 12
      ===== EM models for the G4Region  DefaultRegionForTheWorld ======
       PhotoElectric :     Emin=          0 eV         Emax=   100 TeV

compt:   for  gamma    SubType= 13
      Lambda tables from 100 eV  to 100 TeV in 240 bins, spline: 1
      ===== EM models for the G4Region  DefaultRegionForTheWorld ======
       Klein-Nishina :     Emin=          0 eV         Emax=   100 TeV
etc.

Basically, how do I set Emax to be higher?

(I know that the processes will be inaccurate above 100 TeV. That is fine.)

Thanks! -Tomasz
