RUN # Source/Cosmic/Pedestal Date Start Time End Time HV # of events notes
531 Pedestal Apr 21 2011 3.850V Good pedestal run : ADC vs. chan number , Mean vs. chan number ,RMS vs. chan number
532 Cosmics Apr 21 2011 3.850V Try cosmic with only one paddle. Not successful
533 Cosmics Apr 21 2011 14:38 15:30 3.850V 1103 Make coincidence between small paddle and bottom half of "E" plane, Raised the voltage on the scintillator paddle to 2.15V during run to increase rate.
Gem1 hits with good x and y = 52 good x1 = 59 Good y1 = 92
Gem2 hits with good x and y = 47 good x2 = 49 Good y2 = 118
Gem3 hits with good x and y = 99 good x3 = 111 Good y3 = 192
534 Cosmics Apr 21 2011 15:31 16:20 3.850V 12356 Before run start increase gas flow from 0.2 to 0.4 at flowmeter
Gem1 hits with good x and y = 102 good x1 = 110 Good y1 = 141
Gem2 hits with good x and y = 46 good x2 = 49 Good y2 = 122
Gem3 hits with good x and y = 92 good x3 = 102 Good y3 = 166
535 Beam Apr 22 2011 11:21 12:03 3.850V 52111 Start run before beam and took about 1100 events with no beam. Took data at 1uA with He target. 1D plots of ADC for each GEM plane, Size for each GEM plane, Position for each GEM plane (red is a hit with other plane in chamber) . 2d Plots of Y vx X position for each GEM , Y vx X size for each GEM , Y vx X adc for each GEM , ADC vs size for each GEM plane
Gem1 hits with good x and y = 7620 good x1 = 8342 Good y1 = 11666
Gem2 hits with good x and y = 5454 good x2 = 6189 Good y2 = 10321
Gem3 hits with good x and y = 2616 good x3 = 2945 Good y3 = 6287
Hit in all planes = 1580
Good x2 and y2 = 5454 with good x1 = 4136 eff = 0.758343
Good x2 and y2 = 5454 with good y1 = 4390 eff = 0.804914
Good x3 and y3 = 2616 with good x1 = 2023 eff = 0.773318
Good x3 and y3 = 2616 with good y1 = 2084 eff = 0.796636
Good x1 and y1 = 7620 with good x2 = 4268 eff = 0.560105
Good x1 and y1 = 7620 with good y2 = 5526 eff = 0.725197
Good x3 and y3 = 2616 with good x2 = 1966 eff = 0.751529
Good x3 and y3 = 2616 with good y2 = 2159 eff = 0.825306
Good x1 and y1 = 7620 with good x3 = 2139 eff = 0.280709
Good x1 and y1 = 7620 with good y3 = 3473 eff = 0.455774
Good x2 and y2 = 5454 with good x3 = 1988 eff = 0.364503
Good x2 and y2 = 5454 with good y3 = 2933 eff = 0.53777
Apr 26 2011 April 26th entered hall. Found HV to GEM 1 has tripped off. Could not figure out a quick fix. Took GEM off stack and had RADCON survey.
Apr 26 2011 Install 2nd scintillator in front of GEMs. Setup coincidence, but stupidly left the coincidence in "OR" when in hurry to leave hall.
