845 Filled LN2 cold trap.
1032 Commence data acquisition: 3 series at +/-5 V bias followed by 3 series at -/+5 V, repeated for 6V and 8 V (+/- and -/+); OR trigger on Qi channels only; DIB 1 trigger at 32 ADC bins, DIB 2 trigger at 28 ADC bins; 10/0.1/20 minutes acquisition/flash/cool-down cycle.
1456 Due to reduced event frequency (since triggering only on Qi) data has been stopped.
1624 Filled LN2 cold trap full. Currently: G1=70.1mbar, G2=67.3mbar, 1KPot=1.598K, Lakeshore/MC=69.04mK.
2215 Started helium transfer. Liquid helium in main bath at 8.2%.
Commence data acquisition: flash for 2 hour followed by 2 hours cool-down; 6 series at +/-1 V bias followed by 6 series at -/+1 V; repeat for 1.5V, 2V, 3V, and 3.5V (+/- and then -/+ for each); OR trigger on Qi and Qo channels; DIB 1 trigger at 32 ADC bins, DIB 2 trigger at 28 ADC bins; 10/0.1/20 minutes acquisition/flash/cool-down cycle.
