0009 Start taking data 07110402_0009_F0001. Calibrated -4V on Q1-Q4. 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 30min, flash 20min, cooldown 40min. Flash settings: DIB2, LED 1&2; DIB1, LED1; LED current 0.6mA, 100us ON, 2500us OFF.
Trigger rate was too low. Stop the run and reset timing link.
0013 Start 07110402_0013_F0001
0935 The 'Not enough memory to complete this operation' error occurred again close to the end of the first file. Not sure why. After clicking OK the VI continued to run, but another error window popped up. Some screen shots are here
0953 Flashing started by the DAQ vi. I'll stop the vi and flash for a while.
1235 Fill N2 cold trap full.
1643 Created DCRC_ZeroCharge.vi to set charge channel to the calibrated zero. Turn on LED1 on DIB1 to continue flashing. Tower temperature ~560mK.
1715 Stop flashing detector
1727 Not all the LEDs were turned off. Turn them all off.
1805 Stared taking data 07110402_1805_F0001. Calibrated -4V on Q1-Q4. 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 30min, flash 20min, cooldown 40min. Flash settings: DIB2, LED 1&2; DIB1, LED1; LED current 0.6mA, 100us ON, 2500us OFF.

Calibrated -4V on Q1-4. The cuts are defined as

  • cQ# = max([Q1, Q2, Q3, Q4], [], 2)==#
  • cQCchisq = cQ1chisq & cQ2chisq & cQ3chisq & cQ4chisq;
  • cE = 50<Qsum.
