  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.

Estimation of potential gain by changing. Files from this points are going to rubbish. Potential gains are c. 20% 

22:04: The current acquisition window is recording for 2.9 s. And is not recording for 3.9 s. We are running currently with a spill cycle of 5s every repetition.

22:22 The spill cycle between each injection was changed to 4->3->2s progressively and FRS also stopped taking spills so we settled on 2s spill request.

In the morning the spill request has to be changed back to 5s when the FRS goes back into operation.

The pleiades detectors are now moved into a position which does not disturb the stored beam. 

inner detector: BGO
device: GE01DD2IG 
position: +20mm
scraping beam: not possible

outer detector: GAGG
device: GE01DD2AG
position: -55mm
scraping beam at: -45mm

These positions are fixed, i.e. not moving automatically.

We started playing with the detector pockets of the pleiades arrays at 14:23 01.04.2025.

This might disturb the beam sometimes.

The beam is lost in SIS at 14:35. 

Beam came back at 16:40, we continued playing with pleiades positions until 17:14.
