Shahab | Runs | 72-Ge setting |
the new setting is roughly 400 khz lower in frequency.
Previous beam time Ge was on 243.100 now it is on 242.74
we decided to use the higher harmonic:
expecting it on 244.66 MHz |

Sergey, Helmut | Accelerator | cooler curves for tuning of isochronicity |
Variation of quadrupole E01QS03D to change gamma_t in isoc. mode
measured with 78Kr at 368.5 MeV/u on 28.06.2021 evening.
The shape of the three curves looks very similar they would only require a different beam velocity.
But I suppose we stay with the value close to the old one (gamma_t ~ 1.3956). |
