| | Setup: DIB1/3/4 → SL 27/19/20 → 3.2 MHz filters → cables 2,1,3 → HV board inputs 1,3,2 → HV board outputs 1,2 → DCRC55(1)/50(3). Also DCRC4 is powered and hooked up to control the HV setting. |
| 1030 | Last night's IbIs on DCRC1pA looked pretty good except it railed high. I'll start some test data to try to adjust its offset remotely. |
| 1032 | Start test series at 20 Hz with standard settings |
| 1200 | Took a while, but finally got the DCRC1 baselines all around 0.8 V. |
| 1204 | Begin IbIs data sequence on DCRC1pA with HV=0V from 650 to 300 uA in -1.0 uA steps, 3 seconds of data per step. (IbIsDCRC1pA.msl) |
| | sequence got stuck at 498.0 uA because everything sucks. |
| | moved this data to /byseries/07171123_2500 |
| 1300 | Kill MIDAS, restart MIDAS, start DAQ programs, reset run transition. |
| 1306 | short IbIs sequence test mainly to reset to normal settings |
| 1307 | Start test series at 20 Hz with standard settings |
| 1310 | OK traces look good, try again with the IbIs sequence |
| 1312 | Begin IbIs data sequence on DCRC1pA with HV=0V from 650 to 300 uA in -1.0 uA steps, 3 seconds of data per step. (IbIsDCRC1pA.msl) |
| | sequence continued to completion |
| | moved this data to /byseries/07171123_2600 |
| 1452 | Tower/MC/Coldplate = 25.8/26.4/161 mK, Still = 1.3 K / 0.110 mbar, G1/G2 = 196/187 mbar, 1K Pot = 1.64 K / 27 mbar, MB = 67.7% |
| 1455 | Fill LN2 cold trap full. |
| 1456 | Tweak 1K Pot needle valve a hair. P2 goes off scale - returns needle valve to initial position, nothing happens. |
| 1530 | Tweak it a hair closed, P2 fluctuates but settles around 55 mbar. Tower = 118 mK! |
| 1533 | Adjust driver offsets on DCRC1 PA, PB, PC, and DCRC3 PB, PD. Could not get DCRC3 PC. |
