0028 Still 0W→2mW
0029 Still 2mW→6mW
0106 Power up dcrc. DCRC30→SL19→ZC23→DIB1 and DCRC33→SL20→ZC70→DIB2.
0117 See beating noise on the charge channels. Q2 baseline std = 13ADC, Q4=14.2ADC, Q1=20.8, and Q3=21.3ADC. Set trigger threshold = 60ADC.
0149 Start taking data 07110610_0149_F0001. True -4V on Q1-4, Trigger on Q1-4 at 60ADC. Trace length 0.4096ms (1024bins), lookback time 100us. Data/flash/cooldown = 2h/2h/2h. Tower temperature 146mK.
Can see pulses on the screen.
1112 There was an error occurred after the first data series and flashing. Flashing was successfully stopped but new data series was not started.
1114 Tower temperature 82.8mK. P1=0.11mbar, G1=105mbar, G2=105mbar. Turn off still heater.
1151 Tested the flashing function on DCRC33. Flashing can be started and stopped successfully.
1153 Flashing on DCRC30 also worked fine.
1225 Started taking data 07110610_1225_F0001. True -4V on Q1-4, Trigger on Q1-4 at 60ADC. Trace length 0.4096ms (1024bins), lookback time 100us. Data/flash/cooldown = 2h/2h/2h. Tower temperature 72.1mK.
1229 Found connection to DCRC30 was reset. This might be caused by the DAQ software.
1231 tarted taking data 07110610_1231_F0001 after reinitializing DCRC30. True -4V on Q1-4, Trigger on Q1-4 at 60ADC. Trace length 0.4096ms (1024bins), lookback time 100us. Data/flash/cooldown = 2h/2h/2h. Tower temperature 72.0mK.
1355 Filled LN2 Trap.
2240 Fill N2 cold trap full.
2245 Start baking detector: LEDs 1 & 2 on both DIBs; 0.6 mA; 100 μs on; 5 ms off.
