Agenda
- Operations:
- Run 61 (HV#2) status
- 10keV activation peak now present
- Difficulties calculating phonon collection efficiency…
- operating TES resistance only a little above Rshunt+Rparasitic
- this makes absolute calibration of absorbed phonon energy very sensitive to Rtes and measurements…
- these measurements are not stable or consistent
- Plans for what's next (note: Matt on vacation next week)
- will need more IbIs, dIb/dIs measurements (unfortunately these are time-consuming)
- switch back to HV mode and take data at biases
- look for the lower activation peaks
- calculate Luke gain, verify detector bias
- will have to do flash-and-take manually, no overnight HV data
- Other plans
- Noah's suggestions, including more detailed complex impedance studies
- Further IbIs-type studies. Are the Rnormal measurements stable?
- More noise-versus-HV data
- Characterize “breakdown”
- Run timing, project schedule
- Processing and Analysis
- Run 60, 6“ detector, analysis
- Comparison of UV and IR LEDs
- other items…
- need to get back to work on NSOF, should test whether resolution is improved with new filtering
- Then work on reprocessing old data
- Lab infrastructure
- Welcoming Gina and Jacob, new undergrads, to the crew
- difficulties getting CAEN HV supply to work remotely from linux machines, giving up for now
- Physics
- Measuring low-energy comptons with 88Y, triggering with external detectors
- Low-energy NR peaks from neutron capture in Ge, external trigger
- DAQ and data pipe
- DAQ upgrade soon
- Data storage and backup:
- Need to copy Run 60 data to SLAC
- Need to clean up vuk1/vuk2 before they are retired. Need to ask Angie again when she will finish copying data
- Autoprocessing and data organization development:
- should work on implementing smart processing so that data with different configurations can be processed automatically
- should add more info to database, particularly for potential outside manpower
