-4V, -8V, -13V Ba-133 Data

All figures below show order for individual charges: Top row- Q1, Q2; Bottom row- Q3, Q4
Cut applied to the following analyses: Primary charge channel cut
No strict Chi2 cut was applied to spectra - only simple threshold cuts
For brevity on this page, I supplied links to charge, chi2, and charge stdv. vs event time.

0935 Last run was finished at ~09:02. Tower temperature ~80mK during the run. DAQ worked without problems.
1050 Start taking data 07111205_1050_F0001. -13V on Q1-4. Trigger at 40 ADC bins on Q1-4. Trace length 0.4096ms, lookback time 100us. Data/flash/cooldown = 60/0.1/20 min. Tower temperature 80.5mK. Take +13V data after -13V.
1123 Filled N2 cold trap.

1951 Put the Ba-133 source 6“ below top of mu-shield.
Start to take Ba-133 data after 0.1min flashing and cooldown.
Trigger at 40 ADC bins on Q1-4. Trace length 0.4096ms, lookback time 100us. Data/flash/cooldown = 60/0.1/20 min. Tower temperature 80.5mK. Will take data at -2, +2, +4, +8, +13V bias. 3 series at each bias.
