Entry  Thu May 16 00:37:41 2024, Boguslaw, Camille, Runs, Injection pattern changed 2024-05-16_00-34-07-585_tcl1064.png2024-05-16_01-53-34-896_tcl1064.png2024-05-16_03-10-00-258_tcl1064.png
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)
Entry  Sun May 12 18:34:54 2024, Ruijiu, Analysis, How to use queqiao to transfer tiq data start_OnlineDataAnalysis.jpgqueqiao_rsa.jpg
If the ssh to lxir131 was disconnected, you can connect to lxir131 and restart queqiao program to transfer tiq data from NAS to luster.

1. Open a terminal on any GSI linux computer, like the one in the Measurement Room:
Entry  Sat May 18 00:06:56 2024, Shahab, Runs, HHT people out again 
we try to re run the ESR. ESR behaves very strangely. Something not so right.
Entry  Fri May 17 23:30:16 2024, Shahab, General, HHT people inside 
no beam since about one hour, also HHT people inside since about 10 min.
Entry  Thu May 16 16:43:29 2024, Yuri, Accelerator, HHT 
HHT sees radiation from us. We stop for 10 min for them to see the speed with which the radiation level decreases.

Entry  Thu May 16 08:58:39 2024, Mayr, Hannes, Runs, Fluctuations in particle rate 2024-05-16_08-58-00-964_tcl1064.png
Particle rates are fluctuating and increasing from a constant 5e8 to something around 1e9.
Entry  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. 
Entry  Wed May 15 11:59:32 2024, Beatriz, Min, DAQ, File transfer to lustre looks to be stopped 
File transfer to lustre looks to be stopped at around 11:35AM
Entry  Wed May 15 20:17:20 2024, Jeroen, Accelerator, Fewer spills from SIS18 then lost beam 2024-05-15_20-16-49-990_tcl1064.png2024-05-15_20-18-47-422_tcl1064.png
Apparently fewer spills coming from SIS18, see attached.

Beam was lost at 20:17:52. 
Entry  Tue May 21 08:50:06 2024, Yuri, Accelerator, EoB 
End of beamtime!
Request is out.
Scrapers are removed, slits in the TE line removed, ESR is ramped down.

The cooler curve measured during May 14 afternoon.
Entry  Fri May 17 22:43:11 2024, Jelena B, Zsolt P., Accelerator, ESR_e.cooler are back ESR_back_with_e.cooler.png
We have back ESR and we have a fixed issue with a cooler. 

Beam issues! 
Entry  Wed May 15 13:39:10 2024, Beatriz, Min, General, ESR setting 
From 13:37 ESR will be changed again. Now back to the primary beam, it will be attempted to measure the orbit of the beam.
Entry  Fri May 17 22:38:30 2024, Jelena B, Zsolt P., , ESR + e.cooler are back 
We have back ESR and fixed issue with a cooler.
