|
| ESR is down |
|
Fri May 17 22:38:30 2024, Jelena B, Zsolt P., , ESR + e.cooler are back
|
| We have back ESR and fixed issue with a cooler. |
|
Fri May 17 22:43:11 2024, Jelena B, Zsolt P., Accelerator, ESR_e.cooler are back
|
We have back ESR and we have a fixed issue with a cooler.
Beam issues! |

Fri May 17 22:48:14 2024, 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) |

Thu May 16 19:10:27 2024, 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:

Thu May 16 15:24:30 2024, Ide, Hubbard, Accelerator, new Plunger setting
|
plunger motors were set
to +/-390 mm for 245 MHz resonator

Thu May 16 16:38:11 2024, Ide, Hubbard, Runs, No beam to ESR
|
because of problems in HHT
no beam from 16:36 |
|
Thu May 16 16:45:33 2024, Ide, Hubbard, Runs, Beam returned to ESR
|
beam is back
16:45 |
|
Thu May 16 18:28:31 2024, 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) |

Thu May 16 18:55:38 2024, Ide, Hubbard, General, new timing cycle
|
| new timing cycle of 6.7s |
|
Thu May 16 21:13:18 2024, Ide, Hubbard, Runs, Intensity drop
|
| The intensity dropped at 21:10 from ~ 1.6E9 down to ~ 8E8 |
|
Thu May 16 21:26:50 2024, Ide, Hubbard, Runs, Intensity back to previous values
|
| since 21:20 the intensity is back to 1.5E9 |
|
Thu May 16 21:40:20 2024, Ide, Hubbard, Runs, Intensity drop
|
| Intensity in particles dropped from 21:33 |
|
Thu May 16 21:51:22 2024, Ide, Hubbard, Runs, Intensity back to previous values
|
| since 21:48 particle intensities increased to again to 1.5E9 |

Fri May 17 17:03:39 2024, 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+.

Sat May 18 16:45:15 2024, 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. |
