Reference frame / fixture 2 (can be aligned beforehand) Then fix structure at first detector 1 no variation in height along x and y 3 PMT (can be aligned beforehand) Pin under detector 1. 2 threads, 2 counters.

Reference frame / fixture Aluminum (Wood) plate Held in place by clamp? 1) Align PMT telescope – coincidence rate on scaler – pull plate on table (thread) 2) Align pixel telescope with respect to PMT / beam – held in place (fixture on plate) 3) Cover pixels with box (frame to make setup light tight) How to adjust height of PMTs with respect to the pixel telescope? Dimensions (height) of the pixel telescope from plate – do we have the final telescope? Tube sizes possible (biggest  adjust with foam) Fix plate on table after alignment with beam. -Align pixels with respect to beam (  PMT telescope) – pre-alignment in lab? -Keep in place (no pull from cables) – need reference/fixture -Light tighten (frame around telescope -Easy access without accidental realignment Fixture (semi flexible) - Foam bed for PMT (how hight) ~10cm Scintillator Small dimension, adjusted in height Pin hole for Standard PLT Layer 1 Box to protect against cloth?  cooling? PLT cable fixture

Analog FO studies with ROC-only board Test: How many DCOL's can we resolve in the analog fastout with different DAC settings? Procedure: - Turn on calibration on one pixel - Measure maximum value for the analog signal - Turn on calibration on another pixel two double columns away, i.e., skip a double column - Measure the new max value - Repeat...

Analog FO studies with ROC-only board - Sometimes, once many alternating double columns have hits in them (~7), and we then enable another column between two already active columns, strange things happen Example 1: Multiple TTL FO signals are generated Example 2: The analog FO gets a second hump every once in a while  Today: use the FED readout - optimize ADC range with attenuator - establish take data procedure - optimize 25ns integration window for analog FO
