| 1133 | Started helium transfer. Main bath at 48.2%. |
|---|---|
| 1205 | Commence data acquisition: flash for 1 hour followed by 2 hours cool-down; 3 series at +/-5 V bias followed by 3 series at -/+5 V, repeat for 8V, 10V, 12V (+/- and then -/+ for each bias); OR trigger on Qi and Qo channels; DIB 1 trigger at 32 ADC bins, DIB 2 trigger at 28 ADC bins; 20/0.1/20 minutes acquisition/flash/cool-down cycle. |
| 1210 | End LHe transfer (95.8%) |
| 1230 | Filled LN2 cold trap full. |
