|
2025-05-18 12:00 | | | | | | | | called HKR, reported ESR drop, they checked but see no clear reason, ESR crew will be called for help, see 2nd screenshot |
|
2025-05-18 12:15 | | | | | | | | Sergey called, we should stop requesting after ESR cycle, then send "ganzen Kontext" (ParamModi) and then request beam again |
|
2025-05-18 12:29 | 147 | 205822 | 205828 | 205829 | 0.4 | 1.0 | SC_2025-05-18_07-57-22 | again drop in ESR intensity after injection, SIS18 intensity was increased during accumulation |
|
2025-05-18 12:40 | | | | | | | | we sent "ganzen Kontext" (ParamModi) and then request beam again |
|
2025-05-18 13:04 | 148 | 205821 | 205828 | 205829 | 1.3 | 2.5 | SC_2025-05-18_07-57-22 | looks better now |
|
2025-05-18 13:15 | | | | | | | | stopped ESR cycle, stopped NTCAP, Sergey will check ESR settings, maybe improvement is possible |
|
2025-05-18 13:45 | | | | | | | | ESR cycle running but was interrupted, DRALS was still running, we waited until DRALS end, then started ESR cycle again. We changed time between SIS18 injections from 40 s to 20 s |
