Detectors - what detectors are available diamond / silicone - transport / shipping - 3 ROCs at UT?
ROC Operation / Readout Modules (ED) - what modules do we prepare, test, send to UT - schedule - shipping method
Location H4 - final confirmation of location --> are we on the concrete block? - table measures; height block beam?- can table be placed flat (no height variation) - Availability of power, ethernet ports (2) within beam area / in counting hut
PMT telescope (fixture) – see slide
What modules available / to carry / to ship - walk through setups – see slides

Reference frame / fixture
Aluminum (Wood) plateHeld 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

Box to protect againstcloth? cooling?

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 generatedExample 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
