| | Setup: DIB1/3/4 → 3.2 MHz filters → cables1/2/3 → DCRC55(1)/33(2)/50(3) |
| 1030 | came in to check the channels, they look good still nothing seems to have railed in overnight data. At first I couldn't get the DAQ to start self-triggering when I was looking at the SQUID GUI, I don't know why maybe the rate for self-triggering is a bit high. |
| 1040 | disabled DCRC1 triggers and went to NaI coincidence mode with DCRC4 the only thing triggering |
| 1050 | after a test run I changed to 10-minute dumps by modifying the parameter /Logger/Subrun duration to be 600 (seconds) in the ODB, this should be changed back to 60s when the next data is taken, especially if the rate is such that you'll get more than 10000 triggers in 10m (about 17Hz) |
| 1058 | Start a sequence of 21 1-hour series of 0V data with Frontend Gain = 5/2/5, OG = 8/3/8, with 1000 beginning randoms, with no flashing in between series, NaI front-back coincidence data with a 22Na source in the lead castle behind the cryostat. Triggering only on DCRC4 PhA, the NaI coincidence signal |
| 1113 | Note: 22Na plastic source container is near the NaI detector behind the cryostat. The plastic disk should be restored to the snap-container and the radioactive stickers on the side should be re-affixed. The entire snap-container goes in the plastic bag before returning the source to the safe. |
