| 0058 | Start to take data 07110323_0058_F0001. -4V on Q1-4. Trigger: Q1=48, Q2=51, Q3=75, Q4=59, coincidence time 200us. Am-241. 1024 Q samples, 100us lookback time. |
|---|---|
| 1400 | Stop the run 07110323_0058 |
| 1438 | Zap all squids on ZC70 (DCRC33). before take modulation curves. |
| 1705 | ZAP SQUET ZC23 (DCRC30). |
| 1754 | Modulation curves taken |
<note> SQUET ZC23 and ZC70 SQUID modulation curves </note>
| 1818 | Power off DCRC30 and remove it from ebox. |
|---|---|
| 1836 | Power up DCRC33 after removing DCRC30 |
| 1845 | DCRC33 on DIB2, Q1 noise: 3mVpp, 1.2mVrms, base line is flat. Q3 noise: 2mVpp, 0.9mVrms, baseline wiggles. |
| Swap two boards → DCRC30 on DIB2 | |
| 1924 | Put DCRC33 on DIB1 (SL19) and have a look at the noise of both charge channels. |
| 1938 | Put DCRC30 on DIB2 (SL20) without powering it up. Have a look at the noise of DCRC33 on DIB1. The wiggling baseline came back again. |
| 2107 | Had a look at the charge noise with different DCRC connections. |
<note> DCRC v3 & G101 Charge Noise </note>
| 2109 | DCRC30 is connected to DIB2. DCRC33 unplugged. Flash the detector. Tower temperature went up to 440mK. |
|---|---|
| 2119 | Fill N2 cold trap. |
| 2336 | Stop flashing detector |
