| 0040 | Started data 07110412_0040_F0001. Calibrated -8V 1hour neutralization data after 20min flashing. Trigger: Q1=46(0x2E), Q2=34(0x22), Q3=24(0x18), Q4=29(0x1D). I can see decent synchronized pulses on the screen. The run should be good. |
| 1014 | Filled N2 cold trap |
| 1730 | The last series taken 07110412_1644 ended at 17:57, 13min later than it should stop. I think this was because labview didn't check time in time. Also found the -(1,2,3,4)V cofig was found to be (-1,3,2,4); and -(4,3,2,1)V found to be -(4,2,3,1)V. |
| 2138 | Started 07110412_2138_F0001 after 20min flashing. Calibrated -4V on Q1-4. Trigger: Q1=46(0x2E), Q2=34(0x22), Q3=24(0x18), Q4=29(0x1D). Take data for 10min. This is the first series of 1 hour data set: -4V 10min, 0V 20min, -4V 10min, 0V 20min. |
| 2155 | Started data 07110412_2155_F0001. 0V 20min run. -4V 10min run was stopped successfully. But there was an connection error right at the beginning of he 0V 20min run because of DCRC30 was not disconnected before reconnection. We started taking data after releasing port 5001 of DCRC30. Not sure whether the biases were changed to 0V before this point due to the connection error. |
| 2246 | -4V 10min and 0V 20min data was done. The 0V data has both positive and negative pulses. One way to process this data is to process it twice, cdmsbats will be able to process the pulses with a certain polarity in each pass, and then combine the two data sets and remove the bad fits. |
| 2305 | Ground Q1 & Q3 to chassis and flash using LED1 on DIB1, DCRC30. Tower temperature went up to 386mK. |
| 2350 | Stop flashing detectors. Wait for detector to cool down. |
