| 1047 | Filled LN2 cold trap. |
|---|---|
| Fed Cricket (3 pellets). | |
| 1635 | Put Ba-133 source back in safe. |
| 1743 | Fill LN2 cold trap with a bit more LN2. Looks relatively full. |
| Fed Cricket 4 pellets. | |
| 1808 | MC temperature 81.9mK after the long flashing. G2 fluctuates during the cool down. The temperature is too high to take phonon data. I'll take some charge only data instead. |
| 1929 | Start taking data 07120729_1929_F0001. DIB1/DCRC33 = -2V, DIB2/DCRC32=+2V. Trigger on 4 Q channels at 40 ADC bin. Trace length 0.4096ms, Lookback time 100us. Data/flash/cooldown = 30/0.1/20 min. MC T=81mK. Will take data at DIB1/DCRC33 = -4, -6, -8, +2, +4, +6, +8V and DIB2/DCRC32 = -DIB1/DCRC33 bias. 3 Series at each bias. Am-241 source only. Only 2 DCRC's are used in this run. |
