To get the corresponding energy per bin in each target histogram, following methods are used:
With PIBEAM trigger, fill fastbus ADC from each piece of target into 9
individual histogram. From each histogram, the energy
range corresponding to a pion stop in that target was extracted.
With information obtained above, pick out events meetimg following cuts:
(trig & TRIG_PI_BEAM) && cadc[306+i] < tgt_high[i] && cadc[306+i] > tgt_low[i] && fabs(dtim[280+i]) < 3. && daps[280+i] > 5.Fill DADCs which was the peak closest to the trigger timing into DADC histograms. the peak around 400 bins is due to energy deposited by stopped pions.
Runs used to get above histograms are run36560-run36569(execpt 36562). Energy per bin for each piece target is listed below
