| 0905 | HV = 20.00 V, Vtest = 0.7 mV → Vdetector = 19.7 V |
| 1027 | HV = 20.00 V, Vtest = 0.5 mV → Vdetector = 19.8 V |
| 1029 | MIDAS web interface is down. Use start_daq_umn to restart it. Upon restarting, the sequencer is still running. Looking at the raw data, it appears that the crash happened sometime after 2109 last night and the run just continued taking data and placing dumps into the same folder. This resulted in almost 800 dumps in the 07170406_2109 raw directory. Stop the run and the sequencer manually. |
| 1040 | Begin IbIs measurements. |
| 1420 | Dial HV down to 0 V |
| 1640 | Finish full IbIs in both positive and negative biases for DCRC1pA/DIB1pA/Side1pE. There seems to be an offset in the QET bias 0.
Looks like the true 0 for the QET bias is a setting of -5.9 uA. |
