Mon Feb 19 06:01:17 2024, SHB, JM, JG, Run 42 morning shift 6x
|
07:00
Observed reduction in YR09 presure over last few hours in ML online plot. Beam intensity looks OK but target density was fluctuating quite a
lot. Current value was 1.5e11. |
|
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. |

|
11:05
Confirmed overlap is at 4 mm under new settings.
For unclear reasons, the bottom-left detector is not seeing the halo anymore since around 10:00. Rutherford still visible and if the left arm |
