Task List


  • Run weekly TallBo meetings
  • Send Cary final "lazy susan" specifications
  • Mount SiPMs
    • Practice with SensL SiPMs and write up procedure.
    • Then mount the VUV Hamamatsu SiPMs
    • Determine whether we should start mounting SiPMs on a PCB a la LArIAT or Taritree.
  • Get oscilloscope DAQ working on uboonepab02
    • Check with Joel about crontab and USB wifi adapter
    • Read out dark box setup with LED driven from uboonepab02
    • Post instructions on how to do this somewhere on this wiki
  • Ask the Indiana group whether they have a small data analysis task Stefano can help with for their current TallBo run.
  • Determine how to download PAB gas analyzer measurements.
    • Follow up with script that posts this info to the PAB ECL.
    • Give Stefano a data set in which he can analyze fluctuations in gas analyzer readings.
  • Follow up with Brian about 8-channel digitizer for TallBo
    • Develop artDAQ solution to read out new digitizer
  • Build Stella test setup
    • Develop source and SiPM mounts
    • Develop level monitor
    • Determine if we need to order new alpha sources
    • Procure 80 V low voltage supply
  • Build TallBo test setup
    • Develop mechanical setup for measuring 3rd component of LAr scintillation light in TallBo.
    • Determine how to bias SiPMs for best timing resolution.
    • Determine if we need to borrow a feedthrough from IU and which one (they have already offered to let us borrow their LEMO coax feed-through, but perhaps we need to borrow the bi-axial feedthrough as well)
  • Ask Indiana University what their current usage of the vacuum monochromator and deuterium lamp setup is.
  • Post TallBo LED driver board instructions somewhere appropriate on this wiki.


  • Work with Evan on most of the above tasks.
  • Done: Send dark box design to Matt so he can send it to Len for review.
  • Post Len's dip-coating setup design somewhere appropriate on this wiki.
  • Post splitter circuit documentation somewhere appropriate on this wiki and add information on the LED joiner circuit.
  • Write up a document describing our test of the miniSAS cable
    • Download cable test data from the oscilloscope and help Stefano do an analysis to determine the signal-to-noise ratio for the 2 waveforms.
    • Determine what other information can be extracted from our current setup (max bias voltage that can be applied to a pair of signal wires)
      • Determine if we are actually biasing an adjacent pair of wires in the cable.
    • Understand what has been measured about this cable from BNL (bandwidth, attenuation)
    • Ask Gary Drake and/or Dave Warner how the SiPMs will be read out in protoDUNE and then try to replicate that in our setup
  • In Progress: Determine interest in Raspberry Pi camera paper.
    • Expose Raspberry Pi to Liquid N to see if any components disintegrate at cryogenic temperatures
    • If not, start with purity tests
    • Compare with uboone paper
  • In Progress: Follow up with Josh and Joel about SiPM test stand.
  • Check with Zelimir at ANL how the tested the cables for protoDUNE and what criteria they used to measure the cable performance based on
  • Check with Denver and Zelimir if there are any spare SSPs we can borrow to do our cable tests. If neither works, check with Alex H if we can borrow som efrom 35ton
