Tue May 14 23:40:03 2024, Helmut, Sergey, Yury, Accelerator, paper log book 
|
two pages of log book on paper for teh first setup,
injection into ESR and tuning primary beam 100Mo and fragment 98Mo. |

Tue May 14 23:22:55 2024, Helmut Weick, Accelerator, isochronicity curves
|
Sergey started with a setting with quadrupoles already changed like in 2021.
Ths was used for the first isochronicity curves.
It also gave soem, however, not good peak shapes with scrapers closed.

Wed May 15 19:20:32 2024, Helmut Weick, Accelerator, scraper setting
|
After the orbit correction on the target straight section the scrapers work better.
One pair of scrapers works best:
GEEXDS2HA (outside straight section = low Brho side) = -4.0 mm
|

Wed May 15 19:45:44 2024, Helmut Weick, Accelerator, Cooler curves after beam shift
|
After the Beam position tuning but before the scraper tuning two more cooler curves were taken.
The first with all scrapers open shows a similar shape to before with the same quadrupole setting.
Afterwards the ESR ebergy was shifted by -0.8 MeV/u to get the beam more on an outer orbit.

| We lost the beam for ~2min at (from ~5:28 till ~5:30). Everything seems to be back at the same state. |

Centered resonant frequency on 98Mo+42 at the 126 harmonic (243.925 MHz) and 211 harmonic (408.483 MHz).
Recording for 2 seconds (injection start at 10%), injection every 6 seconds. |

Wed May 15 01:11:45 2024, David, Asahi, Shahab, Chris, Ruijiu, General, Time optimisation
|
DAQ stopped at 01:11 to optimise data taking cycle of RSAs.
Changed data writing time from 2s -> 1.8s. |
|
Wed May 15 01:27:13 2024, David, Asahi, Shahab, Chris, DAQ, Restarted data taking
|
Data taking restarted at 01:27 following re-alignment of the RSAs.
Also reduced number of processing threads to 10. |

Wed May 15 11:45:22 2024, David, Analysis, Lustre Trouble
|
Since around 11:30, Lustre is down, therefore in https://sparc-daq-02.gsi.de/, the spectrograms are not being updated. Expected time to recovery > 2 hours.
The data will still be stored on the local hardisk. Whenever Lustre is online, we start file transfer and analysis.

Wed May 15 06:15:02 2024, Chris, Asahi, DAQ, Data transfer to lustre looks to be stopped
|
File transfer to lustre looks to be stopped at 6:03
File copy program had stopped for some reason.

Wed May 15 02:07:02 2024, Chris G, Asahi Y, General, No beam to ESR
|
Injection to ESR stopped around 02:04:45.
Will continue to write data in hope that beam returns shortly. |
