  157   Fri Apr 4 16:12:54 2025 JG, IDGeneralpleiades detectors moving
We started moving the pleiades detectors at 16:13 04-04-2025.

We have the inside pocket (GE01DD2IG) at 2mm. 
The outside pocket (GE01DD2AG) cannot be moved by the Device Control program, some problem with the tolerance (error message: outside of tolerance). Need to go in in a short break and check what is wrong.

We will partly scrape the beam.

  257   Mon Apr 7 03:25:41 2025 Siddharth, Dima Collaborationmesycontrol does not start GUI
mesycontrol process starts but shows no GUI at all.

Around 02:51 we wanted to record leakage currents for PLEIADES. 
The windows of the mesycontrol were not present on the screens. 

We followed the instructions for restart:
-ssh -X into x86l-128 (-X is important, otherwise qt will not be initialized)
-mesycontrol

as a result we see nothing but the terminal is busy, and the process exists. 
We noticed that ssh connection establishes very slow, the terminal after the connection responds to typing with a delay of several seconds(one press 'm', after 1-2 sec that letter appears on 
the screen).
 
htop hanged the terminal entirely without showing a thing. Several minutes before we started htop and 12th thread(processor?) has been fully busy, 100%.

our assumption is that GUI has been closed because computer had not enough resources for sustaining it. We would not expect such a slow response even in terminal. 
Could anybody have a look on x86l-128 and figure out why is it so slow? 

UPD: started mesycontrol around 03:40, until 04:02 nothing happened except first two commands. 
Tried to start it from x86l-124 and everything works fine except that the connection to /dev/tty/USB0 can't be established (because it is occupied by x86l-128?)
So we are not able to read leakage currents.

~ 20:00 changed E-SIS to 524.0 MeV/u to get 194Pb at the Brho of the primary beam before (=7.2008 Tm).
which corresponds to gamma = 1.400 for 194Pb82+. 
Before it was E-SIS = 480.5 MeV/u after Be-1839 mg/m^2 target Brho = 7.2014 Tm.
Keep target and beamlines and ESR the same, only SIS and TE-line before target is changed.

  53   Tue Apr 1 22:05:24 2025 Ruijiu Analysisanalysis result
This is a preliminary result during 4:00-19:00 April 1st 2025. 
I correct the frequency drift of 194Pb82+ ions injection by injection.

I have analyzed all injection data during 4:00-19:00 and calculated the frequency of 194Pb82+ for each injection. This is the frequency of 194Pb82+ as 
a function of time. You can clearly see that the frequency of 194Pb82+ was drifted from 408.603 to 408.600 MHz. The variation of frequency is about 
3kHz.
