Taking Y-88 data overnight. Last flash at 10:05.
1120 Tower/MC(H35)/MC sensor/Cold Plate = 32.8/27.4/41.8/167 mK, Still = 1.34K / 0.11 mbar, G1/G2 = 114/113 mbar, 1K Pot = 1.71 K / 20 mbar, Main bath = 63.1%
Fill LN2 cold trap full.
1140 Place Y-88 source back in safe.
1150 All pulses still healthy. Cholesterol a little high, though. Dietary changes may be needed if this persists.
1153 Start 30min background 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.
1915 Fill LN2 cold trap full.
Place Y-88 source inside shield ~6“ down.
1923 All pulses look good.
1925 Start 13 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.
