[Clas12_first_exp] New, more complete studies of spring and fall luminosity scan runs

[Stepan Stepanyan]

Dear all,

I just posted a presentation with studies of forward detector charged particle reconstruction efficiency as a function of beam current. I used both spring and fall luminosity scan runs, processed with latex CoatJava (or almost latest). Results are not so different than what we had from August studies. We should dig deeper to understand where the looses come at high currents and see if we can mitigate these losses with. I see few options to explore. In the mean time, I propose to increase beam current for production runs for the remaining of the RG-A run to max allowed value defined by safe operations of detectors. From what I can see from DC currents, we may be able to go to 55 nA.

Regards, Stepan
