| 1900 | Fill N2 cold trap full. |
|---|---|
| 1948 | Checked SQUIDs, no trapped flux. Found DCRC30 phA was actually using the settings for DCRC33 phA. Corrected it and saved the settings in oldDAQSettings_20110531.xml. Timing link and triggers are all set. |
| 2205 | Start taking Cf-252 data 07110531_2205_F0001. -2.5V on DIB1, 2.5V on DIB2. Trigger on 8 phonon channels. 30min data, 0.1min flashing, 15min cooldown. DAQ settings OldDAQSettings_20110531_2204.xml. Trigger threshold 18ADC bin. There seems many pileips. Found LED connection configuration can bring in noise. wr 30 800 seemed to get rid of the noise. The Cf-252 source is 17.5“ from the mu-shield. |
