[Clas12_first_exp] RC meeting at 2:30

[Francois-Xavier Girod]

The spring luminosity scan runs were cooked with 5c.7.0 and are available
under
/work/clas12/clas12/data/calib/cooked_5bp7p0/
see run 4301 to 4308

Also I noticed that I had a missing point in my efficiency graph. I found a
bug in cutting out the beam trips and the absolute efficiency looks more
straight now
It also seems like the 45 nA point is a bit lower as Latifa mentioned it
was taken with different DCHV settings
I updated my logbook post

For completeness, the slopes / FOM based currents I obtained are below. Our
chosen current is compatible with the 2 prong absolute electron rate

Positive tracks slope = 0.493 % per nA / FOM based I : I(1 prong) = 101.4
nA , I(2 prongs) = 67.6 nA , I(3 prongs) = 50.7 nA
Positive tracks slope = 0.477 % per nA / FOM based I : I(1 prong) = 104.8
nA , I(2 prongs) = 69.9 nA , I(3 prongs) = 52.4 nA
Electron rate slope = 0.7 % per nA / FOM based I : I(1 prong) = 71.4 nA ,
I(2 prongs) = 47.6 nA , I(3 prongs) = 35.7 nA
