| 1133 | Tower = 32 mK |
| 1146 | Set -4/+4 V, Start data, but DIB1pB and DIB2pA need to be relocked. Stop data. |
| 1149 | Start background data run |
| 1206 | Stop data, set 0/0 V, flash 30 seconds |
| 1232 | Set -4/+4 V, Start background data run |
| 1249 | Stop data, set 0/0 V, flash 30 seconds |
| 1314 | Set -4/+4 V, Start background data run |
| 1332 | All but 1 channel railed at some point. Stop data, set 0/0 V, relock phonon channels, flash 30 seconds |
| 1421 | Temperature unstable, suspect that it's something wrong with reading the thermometer. Hitting cable from fridge thermometry caused a 2 mK spike. Remove ungrounding adapter from power strip, returning to previous configuration (so that now the PoEs are again connected to wall ground). |
| 1458 | Unplug DCRCs and allow fridge to cool, see if thermometry is stable |
| 1533 | Major temperature excursions continue, 37-94 mK for Tower, also seen in MC, 27-45 mK. These seem real, I doubt it's a problem with thermometry. |
| 1541 | On the other hand, Cold Plate is stable at 138 mK, which is its usual base temperature. This thermometer is on the other cable, sensor 1. Is there a problem with the sensor 2 cable, which connects to the MC and Tower thermometers? No, this doesn't seem to be the issue: because the MC sensor thermometer (RuOx), which is on sensor 1, seems to be also seeing temperature fluctuations. All the MC-level thermometers are showing fluctuations. |
| 1600 | Commence LHe transfer (10.7%). |
| 1608 | When the transfer began, it seems that the base temperature began to behave itself. Tower and MC began to cool at a normal rate. |
| 1610 | MC/Tower = 27/32 mK and cooling |
| 1640 | MC/Tower = 23.9/30.5 mK (best yet I think) |
| 1642 | Cease LHe transfer (93.6%). |
| | Fill LN2 cold trap full. |
| 1713 | Repower DCRCs. Zap SQUIDs. |
| 1745 | Bake overnight. |
