The scraper is blocked at -10 mm and -unfortunately- blocks the beam in the ESR. Uli Popp is taking care.
  44   Fri May 7 11:40:20 2021 Ragan, Andrew, YuriGeneralScraper is fixed - optimisation stage
Scraper is fixed, we start again. Scraper open to let everything through
  45   Fri May 7 12:37:35 2021 Ragan, Andrew, Yuri, AlexGeneralBack with beam
We are back with the beam in the ESR since 12:30
ALL SCRAPERS ARE IN THE ORIGINAL POSITIONS
E02DS3HG = - 35 mm
EEXDS2HA = - 25 mm
EEXDS1HA = - 25 mm
E01DS_H = - 40 mm

For E02DS3HG a reset in the control system needed to be done.

new sextupole setting, isomer not visible yet.
  50   Fri May 7 17:02:51 2021 Kanika, Sergey, Yuri, Wolfram, Michael, ShahabRunsnew sextupole setting 2
There is new sextupole settings, but the scrapers remain like last night (Helmut setting last night.)
  51   Fri May 7 17:12:14 2021 Kanika, Sergey, Yuri, Wolfram, Michael, ShahabRunsEnergy change -6 MeV/u
changed the energy down to 435 MeV/u

changed trigger time back to 50%

last file with 1% trigger: 

245 MHZ 2021.05.07.16.07.03.493
410 MHz 2021.05.07.17.07.21.104


p.s. remember the 245 Analyzer has a 1 hour offset in time stamp because of daylight saving time in win10 setting
  53   Fri May 7 17:35:22 2021 Kanika, Sergey, Yuri, Wolfram, Michael, ShahabRunsEnergy 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:

245: 2021.05.07.16.33.47.178
410: 2021.07.05.17.34.04.780
  54   Fri May 7 18:08:35 2021 Kanika, Sergey, Yuri, Wolfram, Michael, ShahabRunsgoing back to the original energy
going back to the original energy 441 MeV/u

last filenames with the previous energy:

245: 2021.05.07.17.07.00.543

  55   Fri May 7 18:43:13 2021 Kanika, Michael, ShahabRunscave 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.

For the next 2 hours, the operators have changed the spill pattern that as long as they are scanning , we get only every 1 minute, otherwise we get our 15 seconds as usual.

after two hours this situation should be tuned back to the original spill pattern.
