 Fri May 7 04:26:54 2021, Shahab, Runs, 245 MHz resonator extra 20dB gain off
|
made sure that the extra 20dB amplifier is off. |

Tue Jun 29 21:10:30 2021, 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 |

Wed Jun 30 01:38:20 2021, Shahab, Runs, beam is back from Linac but not in the ESR
|

|
Wed Jun 30 02:12:46 2021, Shahab, Runs, still no beam in ESR: quadrupole magnets are down

Wed Jun 30 13:04:40 2021, Shahab, Runs, 245 Amplifier on
|
turned on extra 20dB amplifier for the 245 Resonator around 12:32 |

Wed Jun 30 15:21:44 2021, Shahab, Runs, data synch on WWW server
|
Data is being shared on the WWW server.
Time difference between the analyzers is in order of seconds:
time stamp of the 245MHz data is leading those of 410MHz by 21.733 [s] |

current scraper positions suggested by Sergey:
GEEXDS2HA = -11mm
GE01DS-H (innen) = -58mm |

|
Up to now, attempts to cool the fat line between Se and Ar were conducted. We give up it now and remove cooling |

Tue Jun 29 10:32:10 2021, 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). |
