Laser Station Tests: After return to LANL, the detectors were mounted in a laser station, where we scan them with an IR pulsed laser. In this plot the laser is scanned across the detector (y-axis) and an entry is made for any channel with an ADC signal between 250 and 1000. This scan shows that the channels are grouped by 8 and that their numbering is inverted. Most channels are alive; Some channels are noisy (38,42,55,56,64) and some are dead (34,35,39,40). The gain on the 4th chip (ch 57-64) is generally low.
