• Minutes circulated for review

Speakers: Erwin Siesling (CERN), Joachim Vollaire (CERN)

14:05 → 14:20 Operation Report - REX/HIE ISOLDE update

From SY-BI: From BI’s side this week, the only point to make is that the intervention to replace the XT03.BDB.0400 FC is scheduled for Friday morning. We will also take a look at the XT00.BDB.1900 FC repeller issue, time permitting.

Speakers: Hanne Heylen (CERN), Isabel Frank (CERN), Matthias Alexander Grasser, Simon Thomas Stegemann (CERN)

Physics

• On GPS, ¹⁶²Yb beams were sent to Miniball for the second experiment in their plunger campaign, aimed at measuring lifetimes of excited states. Combined with standard Coulomb excitation measurements, the goal is to determine the deformation of these bands, including possible triaxiality. The experiment has been running smoothly, with no major issues from the machine side, and the users are satisfied. The run will continue for one additional day after the technical stop to complete the Coulomb excitation part of the experiment.

  • RP piquet was called over the weekend

 

Schedule

• Stable beam for Miniball
  • After this run
  •  July/August 

 

 

14:50 → 14:55 Hall activities / Mechanical workshop requests

Speaker: Oscar Fjeld (CERN)

• Working on the IDS beamline for the SPEDE chamber.
  • New supports for cooling device
  • New support for turbopump
  • New clamps for the chamber
  • Adaptation of the cooling system inside the chamber
• Workshop approved by safety
  • Restricted access to who has a signed operator form approved by supervisor and workshop supervisor.
  • Without this you cannot work in the workshop.
• ISS ISO100 flange modification
  • Adding an m6 thread.
• Pressurized air adaptor for the reheating of the Dewars.
  • Look to buy an adaptor to the compressor
• LN2
  • Technical responsible 
  • Safety valves
  • Burst discs 
  • insulation vacuum

 

14:55 → 15:00 Safety, AOB, visits

I would like to announce an AOB for the ISOLDE TC meeting this afternoon. On Thursday I’ll be testing the AUL in 508 at 2pm. All the buttons have been tested previously, so I don’t anticipate any unforeseen power cuts.

I’ll be testing the AUL in the workshop, if anyone else is happy for me to test their AUL (laser labs, solid state labs), please let me know and I will also test them. I’ll do another test in a few weeks to take in any areas I don’t manage to get done this time.

Speakers: Alexander Schmidt, Alexandre Dorsival (CERN), Elodie Aubert (CERN), Hanne Heylen (CERN), Line Le, Melania Averna (CERN), Mia Au (CERN), Nadine Conan (CERN), Oscar Fjeld (CERN), Simon Mataguez (CERN)

ISOLDE - Fresh air ventilation stop 
Working are progressing well, EN-CV plan to finish by 6PM tonight.
If possible they will restart tonight (preferable), if not by tomorrow morning at 8AM.

 

• Flammable gas lines: responsible person - Oscar?
• 508 AUL tests
