Rui-Jiu Chen | Analysis | Comparison of frequency spectrum between 72Ge and other isotope |
This some preliminary analysis results by using NTCAP data. The IQ rate of NTCAP is 20 MSamples/seconds. I analyzed data files recorded from May 7
17:39 to May 8 2:20. The frequency of 72Ge is bended by 4kHz at the beginning of some injections. In order to check whether this frequency bending is
due to isomer or unstable magnetic field. I compare the 72Ge with other isotopes. The similar bending was observed for other isotope in each
corresponding injections. It seems that bend is due to unstable magnetic field. |

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). |

Shahab | Runs | Picture after scraping |
this picture is after scraping by helmut, showing the 410 MHz detector, that is we would expect an isomer where the marker M1 is, i.e. at 2.2kHz on the left side, which we unfortunately don’t see (yet). |
