keyword=Quartz signalsThin (9mg) Carbon target, 3mm by 3mm raster, ~40nA. Note that the Rarm lower quartz signal is amplified and appears a bit noisier than it was last week before the radiation incident. The Left arm signals look good except for the fact that the upper Q cut (red histogram) for the Lower Quartz det seems to show some relative misalignment or ineficiency between the upper and lower dets...the lower det sees events that the upper quartz misses, but this is not the case for the right arm.
