0107 Start taking data 07110324_0107_F0001. -4V on Q1 and Q3. Trigger: Q1(17ADC) or Q3(15ADC). Trace length 1024, lookback time 100us.
0116 The data took by MultiDAQ can not be processed by NoiseGen. Stop the run.
0118 Start taking data 07110324_0118 using the DetectorReadout vi.
0122 There is no second detector in this run. So no filter files should be generated. 07110324_0107 should be good too. But I'll not change the vi.
0929 Stop the run. Can not see much signal. Has it disappeared? Tower temperature 58.3mK.
0940 Fill N2 cold trap full.
1013 Flash detector
1509 Stop flashing
1705 Put DCRC30 on DIB2 (Q1 and Q3) and DCRC30 on DIB1 (Q2 and Q4). Connect timing cable and power up both boards.
1722 DCRC30 had no response. cycle power
2104 Tested auto flashing during the run. It worked fine. Keep flashing.
The templates for processing data crashed. Need to fix that.
2151 Fill N2 cold trap

Data of Q1 and Q3

Cuts

  • cQ# = max([Q1, Q3,], [], 2)==#
  • cQCchisq = cQ1chisq & cQ3chisq
  • cE = 18<Qsum.

Neutralization of Q1 and Q3
The figures below plot the primary events as a function of time. It seemed an accident happened at around
9:25 in the morning cause Q1 and Q3 to loose events. This maybe something in the crystal or the DCRC board.
