Attachment 1: 2024-05-14_21-39-01-112_tcl1048.png

16	Wed May 15 00:26:53 2024	David, Asahi, Shahab, Chris, Ruijiu	Runs	First data file - 00:26
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.
26	Wed May 15 12:58:12 2024	Beatriz, Min, Shahab	Runs	optimizing the mass resolution
Yuri and Sergey still optimizing the mass resolution. From 13:10 to ~ 13:35 SIS energy was increased to 457.4 (~3 MeV/u) to test whether this moves the best isochronicity to 98Mo (we were off before), -> Brho(98Mo)=7.12736 Tm From ~13:35 back to setting up with the primary beam at 441.95 MeV (with target, same Brho as the 98Mo fragments). It will be attempted to measure the orbit of the beam
29	Wed May 15 17:22:43 2024	Jeroen, Shahab, Johan	Runs	98Mo run
Beam tuned at 4:50, data acquisition aligned for 98Mo at 4:56.
32	Wed May 15 18:37:36 2024	Jeroen, Johan, Shahab	Runs	Beam returned to ESR
Beam returned at 18:30:55. Taking data with new triggers.

36	Wed May 15 20:40:51 2024	Jeroen, Johan	Runs	Beam returned to ESR
20:39:42 Runs restarted.

39	Thu May 16 00:37:41 2024	Boguslaw, Camille	Runs	Injection pattern changed
The injection pattern changed on Lassie monitor (0:27 AM). (picture 1) It when back to the previous rate at 1:48 AM. (picture 2) The same pattern change appeared from 3:01 AM to 3:07 AM. (picture 3) and from 3:24 AM to 3:39 AM.

41	Thu May 16 07:25:33 2024	Mayr, Hannes	Runs	Lassie Screenshot 07:23
Start of regular screenshots of the Lassie monitor every 1-2 hours.

42	Thu May 16 07:50:39 2024	Mayr, Hannes	Runs	Peaks with very high particle rate
Peaks in the particle diagram going to unusual high 1.4e9 particles.

43	Thu May 16 08:58:39 2024	Mayr, Hannes	Runs	Fluctuations in particle rate
Particle rates are fluctuating and increasing from a constant 5e8 to something around 1e9.

44	Thu May 16 09:41:56 2024	Mayr, Hannes	Runs	No beam
No beam from 09:39 to 10:10 due to a setting change. The change aims to increase the measurement time to 10s.
45	Thu May 16 10:18:14 2024	Mayr, Hannes	Runs	Beam back, DAQ off
Beam is back since 10:10, but DAQ is turned off to change the setting there. Measurements starting at 10:18 are only test runs and should not be used for analysis.
46	Thu May 16 11:08:27 2024	Mayr, Hannes	Runs	DAQ running again
"Real" measurement with good data starting from 11:07 until approximately 13:00. Measurement time was changed to 10s with injections every 32s.
47	Thu May 16 11:13:05 2024	Mayr, Hannes	Runs	Rates
With the new timing, the rates now look like can be seen in the screenshot.

50	Thu May 16 13:04:02 2024	Mayr, Hannes	Runs	DAQ stopped, change setting to 98Zr
Beam tuning for 98Zr starting at 12:53, following data should be excluded from analysis. DAQ was stopped around 13:13.
