Specific Fall Run 2021 Items

  • High Voltage Mapping. This is a pdf of the excel spreadsheet passed to epics. Contact Ralph Marinaro, Steve Wood or Rachel Montgomery for the actual spreadsheet. [[1]]

How to Documents

  • High voltage and low voltage set up and operation for hodoscope in TEDf with cosmics, including EPICS instructions [[2]]


General Documents

  • BigBite Timing hodoscope Technical Specifications (design and performance requirements), J. Annand et al. [[3]]
  • Software requirements, R. Montgomery et al. [[4]]
  • Original electronics plan, J. Annand et al. (describes chain from PMT to final VME readout, including high voltage and low voltage)[[5]]
  • Scintillator bar and light guide surface roughening tests in Glasgow 2020, R. Montgomery et al. [[6]]

Mapping Documents

  • Updated complete mapping for cosmics running 2021 (G. Penman, May 2021 during cosmic comissioning) [[7]]
  • Updated cosmics mapping spreadsheet (R. Marinaro, G. Penman, May 2021) [[8]]
  • Cosmics channel mapping (R. Marinaro, May 2021 during cosmic commissioning) [[9]]


  • HV patch panels, J. Annand, A. Clarkson [[10]]
  • Schematic for LV distributor panel is found in figure 5 of "Original electronics plan" document [[11]]
  • Schematic for PMT bases is found in figure 3 of "Original electronics plan" document [[12]]
  • Schematic of NINO front end cards is found in figure 4 of "Original electronics plan" document [[13]]

Manuals/Spec sheets for components of hodoscope

  • Electron Tubes ET9124 SB type PMTs [[14]]
  • Eljen Technology EJ200 scintillator bars [[15]]
  • Eljen technology UVT acrylic light guides [[16]]
  • DYMAX optical cure epoxy - check which specific model number was used in Jlab repairs
  • Cage HV connectors at HV patch panel connections [[17]]
  • CAEN V792 [[18]]
  • CAEN V1190 [[19]]
  • CAEN SY1527LC HV mainframe, 19" wide, 8U [[20]]
  • Accessory CAEN A1932AN 48 channel HV distributer modules for mainframe [[21]]
  • Accessory CAEN A1531 primary PSU for HV mainframe - no specific manual online, contacted CAEN and they refer to this document [[22]]
  • AGILENT N5761A DC power supply unit for NINO front end cards, 19" wide, 1U, rack-mountable [[23]]
  • Wiener 6U VME64x 6023 crate [[24]]

Outdated/Preliminary Mapping Below (Just stored here for reference, do not use as of Jan 2021 onwards)

  • Cosmics high voltage and low voltage mapping overview (R. Montgomery, February 2020) [[25]]
  • Cosmics mapping spreadsheet document, take note there are 3 tabs in the spreadsheet. This mapping misses only signal cables from frame to weldment (R. Montgomery, Feb 2020). [[26]]
