 Fri May 7 10:46:40 2021, Yuri, Accelerator, GE02DS3HG
|
| The scraper is blocked at -10 mm and -unfortunately- blocks the beam in the ESR. Uli Popp is taking care. |
|
Fri May 7 11:40:20 2021, Ragan, Andrew, Yuri, General, Scraper is fixed - optimisation stage
|
| Scraper is fixed, we start again. Scraper open to let everything through |
|
Fri May 7 12:37:35 2021, Ragan, Andrew, Yuri, Alex, General, Back with beam
|
We are back with the beam in the ESR since 12:30
ALL SCRAPERS ARE IN THE ORIGINAL POSITIONS
E02DS3HG = - 35 mm

Fri May 7 14:06:02 2021, Yuri, Accelerator, SIS kicker failure

Fri May 7 16:09:50 2021, Yuri, Accelerator, Stop, change of sextuple settings
|
| |
|
Fri May 7 16:17:21 2021, Sergey, Yuri, Wolfram, Shahab, Runs, new sextupole setting
|
| new sextupole setting, isomer not visible yet. |
|
Fri May 7 17:02:51 2021, Kanika, Sergey, Yuri, Wolfram, Michael, Shahab, Runs, new sextupole setting 2
|
| There is new sextupole settings, but the scrapers remain like last night (Helmut setting last night.) |
|
Fri May 7 17:12:14 2021, Kanika, Sergey, Yuri, Wolfram, Michael, Shahab, Runs, Energy change -6 MeV/u
|
| changed the energy down to 435 MeV/u |
|
Fri May 7 17:12:52 2021, Kanika, Sergey, Yuri, Wolfram, Michael, Shahab, Runs, trigger time back to 50%
|
changed trigger time back to 50%
last file with 1% trigger:
|
|
Fri May 7 17:35:22 2021, Kanika, Sergey, Yuri, Wolfram, Michael, Shahab, Runs, Energy change +6 MeV/u
|
We will now go up in energy to 447 MeV (+6 MeV) from the original energy
last file name with previous energy:
|
|
Fri May 7 18:08:35 2021, Kanika, Sergey, Yuri, Wolfram, Michael, Shahab, Runs, going back to the original energy
|
going back to the original energy 441 MeV/u
last filenames with the previous energy:
|
Fri May 7 18:43:13 2021, Kanika, Michael, Shahab, Runs, cave M experiment needs more spills 
|
our pattern causes beam loss while scanning the biological probes in the Cave M bio experiment. They loose every other spill due to high request rate from
ESR.

Fri May 7 19:56:10 2021, Kanika, Michael, Shahab, Runs, ZOOM session restart
|
| restart zoom session |
|
Fri May 7 20:28:32 2021, Kanika, Michael, Shahab, Analysis, Some pictures from the 410 detector 9x
|
| some pics. |
|
Fri May 7 20:34:27 2021, Kanika, Michael, Shahab, Runs, back to 15 sec recording
|
| now we are going back to 15 sec operation. Cave M (bio) operation is over |
|
Fri May 7 22:00:36 2021, Chris, Accelerator, brief beam loss
|
| Brief interruption in beam, ~21:42-21:51. |
|
Fri May 7 22:48:33 2021, Chris, General, still running...
|
| In anticipation of the imminent shift change, a snapshot of how things look. |
|
Fri May 7 23:08:44 2021, Michael, Kanika, Accelerator, Beam issues for short duration
|
| The beam was lost for a few minutes from 23:01 to 23:06. It is back now. |
