PWO CRYSTAL MEASUREMENTS (Richard, Salina)

  • Discussion about Richard's initial results for SICCAS J19 crystal
  • significantly lower light yield overall than measurements from spring 2016
  • some things to check
  • PMT quantum efficiency same as before?
  • Fitting - in particular those as function of position
  • What is included in the error bars shown?
  • Check crystal surface
  • Discussion about Salina's very preliminary results for CRYTUR 01
  • light yield is largely consistent with that measured in summer 2016, but significantly different from that measured in spring 2016
  • some things to check


PWO READOUT (Andres)

  • Received setup from INFN and installed it in the dark box. Next need to figure out trigger and connect things. Expect to have clean signal in one of next meetings.
  • Fixed DAQ - working again now. Will post instructions in Wiki soon.


NPS PMT SHIELDING AND AEROGEL DETECTOR(Arthur)

  • All equipment for PMT magnetic shielding tests transported to test lab and installed in magnet setup. Ready to take data. Expect results at next meeting
  • Discussion about aerogel cover construction and possible exchange of trays before Christmas break ongoing


SHIPPING OF INSTRUMENTATION FROM NEBRASKA TO CUA (Rachel/Aaron)

  • Discussions about details ongoing - stay tuned!


PIXEL DETECTORS AT CERN (Rachel)

  • Successful cool-down of modules to -23degC - actual operating temperature will be a little higher
  • To address condensation, detector will be sealed in a cold box pumped with dry air
  • Shipping of cylinders from Fermilab has been completed - all three half cylinders with disks are at CERN now


DATA ANALYSES (Arthur, Salina)

  • TCS proposal discussions with Marie ongoing - planning to decide on whether or not going forward with full proposal within next month
  • Pion form factor extraction in medium - planning to start detailed work in January 2017
  • Projections for possible pion form factor extractions from kaon experiment ongoing - Salina is cross checking software cuts and simulation limits with Samip


OTHER

  • Discussion about upcoming meetings, e.g. Hall A/C, NPS, High-Intensity Photon Sources, APS April, GHP, ...
  • JLab experiment schedule for 2017
