Beam issues! |

Jelena B | Accelerator | Back to old setting |
We go back to the Zr-settings to make a deffinite state of ESR and we move again to previous setting (Sr) |

Ide, Hubbard, Xinliang, David, Shahab | Runs | New Run setting for Zr Isomer hunt |
19:10 runs from now on run with an optimized setting:
we did a lot of optimization for the hunt of Zr isomer:
1- increased the time as much as possible, but stay within the 1:1 cycle with FRS
2- increased the sampling rate from 6.25 MSPS to 50 MSPS (!) going down to very short recording times --> 300ms only
We are now taking data with this settings for about half an hour. |

Ide, Hubbard | Accelerator | new Plunger setting |
plunger motors were set
to +/-390 mm for 245 MHz resonator
and +/-55 mm for 410 MHz resonator |

Ide, Hubbard | Runs | No beam to ESR |
because of problems in HHT
no beam from 16:36 |

beam is back

Ide, Hubbard | Runs | No beam to ESR |
beam issues between 18:23-18:26
and beam completely lost from 18:27 till 18:32
in the SIS an issue with a dipole occured |

Thu May 16 18:33:30 2024 |
Ide, Hubbard | Runs | Beam returned to ESR |
Beam is back at 18:32
now in the particle plot the peaks seem to be more isolated than before (see attachment 1)
since 18:36 it looks like before (see attachment 2) |

Helmut, Yury | Accelerator | approx. 96Sr setting |
Only 96Sr would yield very few line with only ions from tiem to time.
So we went a bit lower in Brho 7.69 Tm -> 7.65 Tm.
The setting is calculated as a 98Mo39+.
E-SIS = 455.3 MeV/ for 100Mo.
after target 98Mo now with 39+ gives 7.6500 Tm.
In ESR also 39+.
In LISE we get the same average gamma as before for 98Zr (gamma = 1.40082). |

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. |
