1000 The DAQ program didn't finish taking data properly. The files are there, but the quitting process had an error. Had to force quit the program.
1007 Begin flashing detector on Dibs 1 and 2 with both LEDs.
1010 Filled LN2 cold trap.
1025 Fed Cricket 4 pellets.
1035 Begin LHe transfer (15.4%).
1103 Stop flashing detector. The temperature had reached 131 mK while flashing.
1140 End LHe transfer (90.2%).
1145 Restarted LabVIEW. Ba-133 source was not clear in +/-4 V series. Maybe DAQ had something to do with it.
1151 Begin taking data 07130201_1151. Dib 1/2 biased at +/- 4V, +/-3 V, +/- 2V at 30 min each, with 6 seconds of flashing and 20 minutes of cool down in between each series. End with 30 min of flashing and 20 min of cool down. Trigger on Qi/Qo on Dib 2 only at 40 ADC bin. Using Ba-133 source.
1601 Data collection was not good. Still suspecting the switch. Stopped flashing detector.
1634 Start flashing detector again. Using different external PoE supplies but connected via switch. Qi on Dib 3 looks noisy, but I think this is to be expected.
1640 Stop flashing detector. Temperature was still increasing, but was currently at 150 mK.
1230 Filled LN2 cold trap.
