| | Current setup: iZIP mode, DIB1/2/3 → cables → 3.2 MHz filters → DCRC55/33/50. |
| | Overnight: DCRCs off. Cf source near detector for activation |
| 0930 | Tower/MC(H35)/MC sensor/Cold Plate = 30.6/24.0/46.7/139 mK, Still = 1.17 K / 0.10 mbar, G1/G2 = 165/135 mbar, 1K Pot = 1.72 K / 22 mbar, Main bath = 67.2% |
| | With the DCRCs off, Still Temperature and Cold Plate Temperature are reading lower than before. But still pressure is the same - so maybe DCRCs are causing some interference that's causing the Fridge Out 1 cable's thermometers to read high? Meanwhile MC Sensor Temperature (also Fridge Out 1) is higher than recent readings. Something confusing going on. |

| 1310 | Repower DCRCs for some MIDAS tests |
| 1600 | Try zapping SQUIDs using MIDAS tool (http://jiajin.spa.umn.edu:8081/ → DCRC_UI → Tools → make sure zap settings are correct → ZAP) |
| 1605 | MIDAS ZAP didn't work because it didn't like my zap on/off settings of 2 and 30 - it requires 2.01 and 29.99. |
| 1610 | Try MIDAS ZAP again |
| 1615 | MIDAS ZAP failed again - no temperature change or still pressure change, so I assume it didn't work. Stop MIDAS, back to LabVIEW |
| 1625 | Zap all the SQUIDs |
| 1630 | Set up timing link |
| 1650 | All channels set to standard settings, front end gain 5/2/5 output gain setting 3. No noticeable low frequency noise patterns. |
