| | Setup: iZIP mode, DIB1/2/3 → cables → 3.2 MHz filters → DCRC55/33/50 |
| | Taking Y-88 data overnight. Last flash at 07:45. |
| 1020 | Tower/MC(H35)/MC sensor/Cold Plate = 32.5/26.1/42.8/164 mK, Still = 1.25K / 0.12 mbar, G1/G2 = 114/118 mbar, 1K Pot = 1.70 K / 18 mbar, Main bath = 18.6% |
| | Fill LN2 cold trap full. Place Y-88 source back in safe. |
| 1040 | Commence LHe transfer (15.0%). |
| 1140 | Cease LHe transfer (93.1%). |
| 1700 | Fill LN2 cold trap full. |
| 1701 | Bath level at 85.9%. |
| 1705 | Place 88-Y source inside shield ~6“ below top. |
| | Place 3' rubber hose onto LHe transfer port at top of Main Bath. Plug other end with rubber bung. See if this effects tachonis oscillations. |
| 1934 | Bath level at 81.1%. |
| 1935 | Check phonon pulses. Low frequency noise is present, so let's see if the range of main bath levels affects it differently than before. |
| 1940 | Start 18 cycles of 30min 88-Y series at +4/-4V with FG=5/2/5, OG=3, with 1000 initial randoms, 1000 ending randoms, 30s flash and 25 minute cooldown before series. Trigger on DIB1 phA with threshold of 30ADC bins. |
