Target density is hovering between 2.0e-8 and 2.3e-8

  242   Tue Feb 22 19:28:35 2022 David, Yurivacuum

At 19:10 Frank called us that vacuum in sections 08 and 10 got worse by about 1.5 times. There is a possible danger that vacuum valves can get closed if rest gas pressure is above the set treshhold.

Nikos warmed the cryostat by 0.5 degrees from 129.0 K to 129.5 K and the pressure became better than before. We cooled the system in steps of 0.1 degress down to 129.1 K and again observed the pressure rise.

We think we can stay with the present conditions. However, the pressure shall be monitored not to hit the treshhold.

  354   Tue Mar 1 19:41:24 2022 PM, LVtarget temperature walkthrough

A target temperature walkthrough has been initiated at 20:41 since the target density at S1 had slightly decreased (with ~0.1-0.2)

Current temprature 116K

set to 126K at 20:41

set to 95K at 20:47:30

set to 108.5K at 21:01:30, at this temperature was a sweetspot observerd for target density.

set to 109.7 at 21:08:30

set to 110K at 21:13:30 - we keep at this value for a while. the values at S1 are changing between 2.2-2.9e-8

  534   Tue Feb 20 08:41:08 2024 OF, AGstill no beam CRYRING

We have mosty empty injections into CRYRING. Only sporadically the beam with good intensity is injected.

Michael Lestinsky is currently working on the problem.

  750   Mon Jun 16 11:12:22 2025 JG, AK, AR, EHrun 83

12:15 restarted measurement with target - Run 83

same settings as for runs 76, 77 etc

ROOT histograms NOT zeroed

Beam at 8e8, target density at 1.5e13, scintillator @ 0 deg. peak rate 5000

status screenshots attached

15:15: Checks all ok, peaks are peaky (attatchment 8)

16:45 Checks all ok.

17:45 Checks all ok. IMP Froze and has been restarted. Peaks good. Light turned off iin cave.

18:40: Checks all ok. Target great at 1e13.

22:20 Checks done - all okay except aida green-to-red was not working, but still writing data to disk. Carlo trying to figure it out now. All other checks were okay. Daedalus crashed, restarted and target still at 1e13.

Run 24 running

27/05/2025

We start a new run with real data taking condititon: beam is ok, target density is 5e11 cm-2, detectors are moving in-out periodically.

Cooler voltage setpoint 1128.55 V.

Beam energy = 1.99 MeV/u (from HKR)

Attachment 1 - beamcalc with set values

Attachment 7 - beamcalc with actual values

 

Left arm at 18.86 mm

Right  arm IN at 83.69 mm (OUT 37.56 mm)

vertical beam position 0.0 mm

horizontal beam position  -3.5mm

Beam intensity ~2e+7 particles.

Target density ~5e11 at/cm2

Target temperatures: T1=31.5 K T2=35.1 K

Beam cycle set to 10 seconds.

17:32 all checks OK

17:35 target density jumped to at 9e11

19:30 all checks OK (spectra attached)

19:45 target density drops to 3.5E11

20:20 target density jumps to 7e11

21:30 all checks OK

22:50 all checks OK

just FYI: current positions saved in files are x=1000 and y=-750. this information is good in case of crash.

  325   Mon Feb 28 07:35:51 2022 JGcurrent logger crashed

The current logger did crash in the evening of 25.02. and stopped logging since then, it seems.

I restarted it now (28.02. 8:30).

Seems to run stable for now.
