  1. 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 Timeline Updates on setups / measurements Dmitry

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

  3. Reference frame / fixture • 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 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. Box to protect against cloth?  cooling? ~10cm PLT cable fixture Pin hole for Standard PLT Layer 1 Scintillator Small dimension, adjusted in height Fixture (semi flexible) - Foam bed for PMT (how hight) 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)

  4. Setup break down into modules (responsibilities) -> Detector -> PMT telescope / Trigger -> FED readout / ADC card -> Digi Oscilloscope

  5. Detector: This equipment will be in vicinity of detectors – can be placed on table flexible connection between detector and test board (length = ?) - 3 layers (ROC+detector, HDI mounted to frame) - flat cables to connect to test board - Test beam test board (TBM + FO + ) - 3 fast out analog  3 coax cable, BNC connector  FED, Osci (Split? We do) - 3 fast out digital  Trigger - external clock from TTCI (NIMTTL); 2x coax, lemo - FEC board - ribbon cable - HV Keithly – up to 500V (can 220V – power cable) - coax cable, banana to BNC connector? - 2x 5V power supplies (Aligent – available for 220V – power cable) - test beam board, FEC board  power cables - TTL pulser (can 220V – power cable) - 2 coax cables (2m), T-connector • Rutgers - please ask others to bring equipment (you cannot provide) • What comes from UT (goes there first)

  6. PMT/Trigger: This equipment will be in vicinity of detectors – can be placed on floor connection length 2m - 2 PMT + scintillators (one with dimension <1cmx<1cm) - NIM crate - HV supply (2 channels; up to ~1.7 kV) NIM - 2 HV supply cables - 2 readout cables/BNC  Lemo - lemo cables (5x30cm+5x1m) for timing adjustment (delay unit?) - lemo cable connectors - Discriminator 2 channels (has 4) / alternatively CFD NIM - 2 coax cables + lemo connectors - 4 Quad coincidence unit NIM - 2 coax + lemo - Level translator NIM (8)  TTL (8) LeCroy 688AL NIM (12 ns delay) delays PMT TTCI Test board NIM  TTL Trigger in Bob Richard Bill TTL  NIM Coinci Dscr FO digital layer 1(2,3)

  10. Timeline - 17 May – 24 May at H4 Prevessin, CERN

  11. 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...

  12. Test Findings (Matt) Can't resolve levels by max value #:Integrals (x10E-9)‏ 1: 1.6 2: 2.9 3: 4.0 4: 5.0 5: 5.8 6: 6.5 7: 8.5 #pixel:Integrals (x10E-9)‏ 1: 1.5 2: 2.8 3: 4.0 4: 5.0 5: 5.9 6: 6.7 7: 8.3 Case 2: - VIColOr: 100.4 uA - VnPix: 8.5 uA - VsumCol: 47.6 uA Heights Resolvable: 7 Case 1: - VIColOr: 100.4 uA - VnPix: 8.5 uA - VsumCol: 31.8 uA Heights Resolvable: 6

  13. 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
