- Lab Update - Run 76 in progress
- Ladder calibration seems to work but produces some strange results:
- at V_bias = -21 V, empirical NTL gain only 4.45 (implies 13.1 V)
- at V_bias = -65 V, can't fit the spectra UNLESS high-width pulses are cut out. Then spectra fit with NTL gain only 7.5 (implies 25 V)
- similar result for -84 V data
- if this calibration is right, resolution is much worse than previously thought: noise sigma ~ 25 eVee
- More work needed: data quality cuts, check rates for write efficiency, check efficiencies more carefully
- NaI-coincident data
- looking at -84V NaI-triggered data: SiHV spectrum not showing clear evidence of signal
- above plot: 12 hours of data, cuts to remove high-width events and Am-source events (phi-delay cut) and selection for coincident timing window (PTOF_delay)
- This weekend took similar data with PuBe source removed
