| Setup | DIB1/2/4 → 3.2 MHz filters → cable 1/2/3 → gender changer 1/2/3 → movable source controller/board with external Feedback resistor/nothing → DCRC55(1)/DCRC33(2)/DCRC50(3) |
|---|---|
| 1155 | Fill LN2 cold trap full. |
| 1200 | U02844 = 0.0342, X12004 = 0.182, H35 = 0.0293, Still = 0.00585, MC/Coldplate = 30.9/30.5 mK, G1/G2= 215/196 mbar, 1K Pot = 1.65 K |
| note: several mistakes in the above measurements - the temperatures are probably all from the Tower thermometer (U02844) but using different calibrations. | |
| 2043 | Start 4x S1/S2=+4/-4,-4/+4 V loop of 30 min Bkg data series, Driver gain = 1, with 1000 initial randoms, with 30s flashes and 30 min cooldowns trigger on DCRC2pA/B/C = 8/8/8 ADC using sequence qbias_pm4_mp4_loop.msl |
