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
- Statistics and fitting
- Check conditions for earlier CRYTUR01 measurements
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
