Mon Jun 2 16:35:35 2025, EW, AG, Run 42 and scraper tests
|
17:00
Scraper tests conducted. We tried moving in the scrapers both at a fixed position throughout and also moving with the injection cycle.
We were unable to find a good position with the scrapers that did not produce significant scattering in the detectors. |

Mon Feb 19 21:46:32 2024, EH, EM, CB, Run 45 + end of late shift 14x
|
22:54
We have moved the gas jet target out (y=4000), the density has dropped to zero.
Started a new run (Run45) for background measurement.

|
At 19:10 Frank called us that vacuum in sections 08 and 10 got worse by about 1.5 times. There is a possible danger that vacuum valves can get closed
if rest gas pressure is above the set treshhold.
Nikos warmed the cryostat by 0.5 degrees from 129.0 K to 129.5 K and the pressure became better than before. We cooled the system in steps of |

Recently the pressure started to raise a bit, we have increased the temperature from 129.1 K to 129.2 K. Current pressure at S1 2.10e-7.
Merger, Tape server (WS3) checks: DONE, writing ~1 MB/s, refreshing is fine
