End of beamtime!
Request is out.
Scrapers are removed, slits in the TE line removed, ESR is ramped down. |

Oliver, Jelena | General | Shift news |
Data collection runs smooth so far.
Yuri Litvinov will start modifying SP magnets now. The resolution will change. |

Yuri | Accelerator | Modify SP magnets |
In attempt to remove double-peak structure, we will modify the SP magnets
START: 9:02
SP unchanged. Other values lead to a worse peak shapes.
Scrapers:
EEXDS2HA: -75 mm -> -5 mm (hopefully the left half is scraped)
E02DS3HG: -60 mm - unchanged
STOP: 9:40 |

Gregor, Cagla | Accelerator | Short beam interruption |
We lost the beam for ~2min at (from ~5:28 till ~5:30). Everything seems to be back at the same state. |

Shahab, Kanika,hongfu li,xing xu | DAQ | center frequency change for 96Sr |
aiming for 96-Sr:
410 MHz:
The plunger position for 410 is 45, which should correspond to the 408.998 MHz which is expected position for 96Sr. The first file is at 14:38.
245 MHz:
The center frequency is changed to 244.235723 MHz for 96Sr, the new plunger position is 300.The first file is at 14:5 |

Yuri, Sergey | Accelerator | Sextupoles |
at 13:00
scrapers in the ESR are moved to block the most outside orbits
E02DS3HG out -> -60 mm
EEXDS2HA out -> -75 mm
at 13:50
E02KS3 changed from +0.01 to -0.1
E01KS4 is unchanged at -0.26
peaks look somewhat narrower (see telegram) |

Helmut, Yury | Accelerator | setting for 96Sr (98Y) |
To have a few more lines the setting actually is not on 96Sr directly, but on 98Y39+.
98Y is also the one set to be isochronous.
But in addition the SIS-energy is shifted by -0.9 MeV/u to get at least better transmission for 96Sr. |
