| 1042 | Filled LN2 Cold Trap. |
| 1142 | Started data 07110411_1142_F0001. Calibrated -4V on Q1-4. Trigger: Q1(60ADC) OR Q2(36ADC) OR Q3(30ADC) OR Q4(30ADC); coincidence time 50us. Trace length 1024, lookback time 100us. DCRC30 on DIB1, ZIP2, master; DCRC33 on DIB2, ZIP1, slave. Auto run enabled, take data 15min, flash 20min, cooldown 40min. Flash settings: DIB2, LED 1&2; DIB1, LED1; LED current 0.6mA, 100us ON, 2500us OFF. Tower T 60.5mK. |
| 2028 | The timing link of the data took after +6V bias sweep wasn't set correctly and a large fraction of the data was noise. I modified the SCDMS_DetectorReadout.vi to have a look at the baseline standard deviation. So I can set my trigger level as a number of sigmas away. |
| 2031 | Q1 baseline std: 15.20ADC. Q3 baseline std: 8.05ADC. Q2 baseline std: 11.20ADC. Q4 baseline std: 9.50ADC. |
| | I will set trigger level as 3sigma. Then they are Q1=46(0x2E), Q2=34(0x22), Q3=24(0x18), Q4=29(0x1D). |
| 2049 | Checked timing link from the readout vi: OK. Checked trigger settings from terminal: OK. |
| 2053 | Started data 07110411_2053_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. |
| | Will take -7V to -1V in -1V step and -(1,2,3,4)V and -(4,3,2,1)V data overnight. |
| 2104 | Filled N2 cold trap. |
| 2134 | Stop the DAQ after 15min data and 20min flashing. Had a look at the data. Timing link and trigger levels both were OK. Q4 had the most events. Q1 and Q3 didn't have so many. |
