[Clas12_high_luminosity] CLAS12 Luminositiy Upgrade Meeting - follow up

[Whitney R. Armstrong]

Hi Maurizio,

Thanks for the information. What is not clear from the presentation is how 
exactly you arrive at a given luminosity.

Do you just calculate the flux of electrons for a given time interval and 
simulate that number of events? 

The Moller process would be part of geant4's ionization process.

Cheers,
Whit
