Yuri | Accelerator | GE02DS3HG |
The scraper is blocked at -10 mm and -unfortunately- blocks the beam in the ESR. Uli Popp is taking care. |

Ragan, Andrew, Yuri | General | Scraper is fixed - optimisation stage |
Scraper is fixed, we start again. Scraper open to let everything through |

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
EEXDS2HA = - 25 mm
EEXDS1HA = - 25 mm
E01DS_H = - 40 mm
For E02DS3HG a reset in the control system needed to be done. |

p.s. remember the 245 Analyzer has a 1 hour offset in time stamp because of daylight saving time in win10 setting |

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.
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. |
