| 0006 | Started taking data 07110331_0006_F0001. -4V on Q1-4. Trigger: Q1(30ADC) OR Q2(30ADC) 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 60min, flash 20min, cooldown 40min. Flash settings: DIB2, LED 1&2; DIB1, LED1; LED current 0.6mA, 100us ON, 2500us OFF. Tower temperature ~62mK. |

| 0919 | Labview stopped at File 9 of series 07110331_0607 because 'not enough memory'. There might be a memory leak. Have to kill Labview to end it. |
| 0930 | Filled N2 cold trap. Tower T=61.7mK. |
| 1059 | Started flashing the detector. All 3 LED's used. 0.6mA, 100us ON, 2500us OFF. Tower T rose up to 540mK. |
| 1239 | Stop flashing detector. |
| 1329 | Start to take data 07110331_1329_F0001 after 40min cooldown. -6V on Q1-4. Trigger: Q1(30ADC) OR Q2(30ADC) 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 temperature ~60.5mK. |
| 1413 | A power glitch occurred during the cooldown after flashing. The temperature went up. Both pumps stops. I started them right away. This caused about 7min delay in the cooldown. I'll pause the vi for additional 7min. |
| 1830 | Start to take data 07110331_1830_F0001. -8V on Q1-4. Trigger: Q1(30ADC) OR Q2(30ADC) 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 temperature ~65mK. |
| 1936 | Filled N2 cold trap. |
| 2320 | Changed the DCRC setup from indicator to control in DCRCv3MultiDAQ.vi and the settings can be changed from the front panel. |
| 2334 | Start to take data 07110331_2334_F0001. -2V on Q1-4. Trigger: Q1(30ADC) OR Q2(30ADC) 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 temperature ~63.4mK. |
-4V 1 hour Neutralization
Data: Series 07110331_0006, 0206, 0406, 0607
Don't know what happened in the seires _0006. We decided to take 15min of data and use the same flashing scheme. Take 4 datasets for each bias.
The cuts are defined as
- cQ# = max([Q1, Q2, Q3, Q4], [], 2)==#
- cQCchisq = cQ1chisq & cQ2chisq & cQ3chisq & cQ4chisq;
- cE = 50<Qsum.
