Revision as of 11:10, 15 November 2012
Prototype at 2100V, 50/50 Ar/CO2
Trigger signals
Histograms of threshold-crossing bins in central bank of 16 straws, different thresholds (ignore the histo titles)
Histograms of ADC value=100 threshold-crossing bins in individual straws (search started at bin 160)
2-d histograms of ADC value=100 threshold-crossing bins in each straw vs same for one particular straw (The histos in each image (set of plots) are arranged as in the prototype but the sets of plots are not).
Same data after more normal analysis (Search forward to find pedestal+5sigma crossing, then backwards to find 4sigma and then 1sigma crossings)
Noise run (triggered on 20us pulser) ADC=100 crossing bins
Noise run (triggered on scintillator when prototype was not above/beneath it) ADC=100 crossing bins
