| | Overnight: weak Y source placed on NaI detector mount on fridge shield |
| 0930 | Remove weak Y source from NaI detector mount |
| 0935 | Place strong Y source on south wall near NaI detectors. This raises event rate in detector to about 60 Hz |
| 0935 | MC = 33.0 mK. Main bath = 30.0% |
| 1000 | Finish IbIs on DCRC1pA/DIB1pA/Side1pE |
| 1005 | Fill LN2 cold trap bath. |
| 1030 | Tower/MC/Coldplate = 32.9/30.8/194 mK, Still = 1.3 K / 0.110 mbar, G1/G2 = 246/221 mbar, 1K Pot = 1.691 K / 28 mbar. Main Bath = 28.6%. Boil off rate: faster than slow mode (predicted level: 32.3%) |
| 1045 | Finish IbIs on DCRC1pB/DIB1pB/Side1pB |
| 1055 | Start LHe transfer (MB = 27.8%) |
| 1205 | Finish LHe transfer (MB = 90.6%) |
| 1213 | Try external triggering from NaI setup. Enable DCRC4 in ODB and make it timing master. Turn off DCRC4 15V power to be nice to OP Amps. We can see and trigger on TTL signal on DCRC4pA. |
| 1218 | 60 kHz noise observed on all phonon channels. Reset timing link via telnet session, but the noise remains. |
| 1223 | Hopefully we can sort this out. For now, just start taking some data to search for coincidence with the NaI detectors. |
| 1224 | Start 0V test coincidence series with 1000 ADC trigger on DCRC4pA (TTl signal) . |
