keyword=Analysis: 1X pos - 1X neg study
I have studied 1xp - 1xn distribution and 1X plane multiplicity without
any ADC gates. (time zero is adjusted)
If time zero is adjusted, |pos-neg| can be used for selection of good
timing from multiple hits.
Fig1 is Run 75251 5uA carbon 4/4 (1X1Y2X2Y)
Plane multiplicity (top) and with pos-neg time difference < 3ns (bottom)
Fig2 is distribution of T(pos)-T(neg). (Log and Lin)
Fig3,4 are the same for Run 75232 30uA on C.
Higher current caused a little bit higher multiplicity.
