| 11:40 | Stop flashing. MC temperature drops and plateaus at 103.5 mK. LED1: -4.72 V; LED2: -0.75 V. |
| 11:46 | Reset DCRC to disable the LEDs. LED1: 50 mV; LED2: 23 mV. |
| Tune and lock squid. Phonon and charge settings are in the table below | |
| 12:17 | Start to take data with a Cs source. |
| 13:17 | Stop take data. Got 190 files and 2.84 G. Channel A may lost lock during the run. |
| 16:57 | Measure voltage transient at SQUID locking. Take data run001 to run004. |
| run003 and run004 |
