two pages of log book on paper for teh first setup,
injection into ESR and tuning primary beam 100Mo and fragment 98Mo.

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.
But after a failure only a new setting of quads could revover the peaks.

Then more cooler curves were measured and found to have quite a slope.
Changing ESR energy does not change the curves much, but changing the quads does.
With the stronger variation of quads (+1.65% on two quadrupole families) the curve tilts to opposite side.

All curves in EXCEL.
Cooler voltage converted to Brho with gamma ~ 1.4 and curves in relative frequency spread shifted on top of each other.
In new injections the quads are set new, which causes a frequency jump. Pasted parts of curves to remove jump.

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
GE02DS3HG (outside arc              = high Brho side) = -71.4 mm
All other scrapers are open (finished playing with scrapers ~18:20)
When one side is opened more one can cut more on the other.
We can attack the beam from both sides.
With scrapers good resolution, David already posts lifetimes of the isomer.
Details in paper log book.

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.
The curve then is shifted and has a bit less acceptance.

until we lost the beam in the night.

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

RSA file sync with server was up with LXIR131 through to the Lustre.

empty shots for test.

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. 

DAQ stopped at 01:11 to optimise data taking cycle of RSAs. 
Changed data writing time from 2s -> 1.8s.

Data taking restarted at 01:27 following re-alignment of the RSAs.

Also reduced number of processing threads to 10.

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.

Attached can be found an information email sent:
-------------------
Dear Lustre-users,

the main metadata server of the Lustre file system shows repeated errors that break I/O on at least
some clients.

We will have to restart the server, which will cause a downtime of min. 2 hours.
-----------------------------------------------------------------------

File transfer to lustre looks to be stopped at 6:03

File copy program had stopped for some reason. 
After figuring out what the problem was, we have restarted the file copy and everything seems to be catching up.

Injection to ESR stopped around 02:04:45.

Will continue to write data in hope that beam returns shortly.
