keyword=triple coincidence
Triple coincidence so far.
I chained all the files that we have
3026-3040, 3043-3053, 3056, 3058-3059, 3061-3064, 3065, 3067-3068,
3070-3071,3073-3074, 3076-3081, 3083-3084, 3086 - 3091 .
I have ~ 0.9 C
For run # 3065 we don't have end of run info, so the I only estimated the
charge for this run based on the time and current.
three plots attached:
1) Coinc between 2 HRS.
2) triple in BB
3) triple in HAND
number of events: e,e'p ~ 4300
e,e'pp ~ 32
e,e'pn ~ 110
cut that I used for HAND: DBB.edtpr[0]==0 && abs(L.gold.dp)<0.05 &&
abs(R.gold.dp)<0.05 && DBB.evtypebits&(1<5) &&
abs(DBB.lt3[0]-DBB.lt1[0]-561)<10
cut that I used for BB: DBB.edtpr[0]==0 && abs(BB.tp.e.tof[%d]+354)<7 &&
abs(DBB.t3[0]-390)<230 && sqrt(BB.tp.e.LE[%d]*BB.tp.e.RE[%d])>400 &&
sqrt(BB.tp.de.LE[%d]*BB.tp.de.RE[%d])>150 && abs(L.gold.dp[0])<0.05 &&
abs(R.gold.dp[0])<0.05 && abs(DBB.lt1[0]-DBB.lt3[0]+561)<11
