Minutes from ISOLDE Physics Group meeting, 10^th June 2015.

There were no comments to the minutes from the previous PG meeting last week. 

Technical news

• HRS
  
  • IDS did not have a good run. Bad yield of ^67-68Mn from the target
  • One more test of the target is ongoing. This target was the one that crashed into the front end.
    • Could be outgassing or the heavy contamination from the Rubidium mass marker.
    • IDS and COLLAPS saw a better yield for fewer protons, which is still not understood.
  • COLLAPS had a good run and a successful collaboration with the RILIS team who provided the laser for optical pumping in the ISCOOL, and completed their program with the exception of ⁶⁵Mn. 
  • Note that the software has lately displayed the High Voltage as OFF, when it is actually ON. This has to be checked manually.
  • Magnet cycling is not behaving and there are issues, the cycling stops or does not respond.
• GPS
  
  • Technical stop planned Monday at 8:00, so GPS will stop at 5:00.

Control system will then also be updated.
Will start up again Tuesday evening.

• HIE
  
  • Starting the cryo-module is looking good and is now entering the more critical step of cooling it down.
• B-508:
  
  • The ¹¹¹Cd run is a good test of the new SSP-labs.
  • The chemical fume cupboard is currently being installed.
  • The ventilation system is only an On/Off system not to be regulated (not ideal).
    •  Thursday morning it will be inspected.
  • The LASER labs are now with installed sensitive equipment and closed for any installation work in 508 (without consultation before entering).
  • Phones are working and now with the PIN codes.
  • The open broken door – in progress on repair. LASERS do not seems to be affected by temperature variation from the open door (at the moment).

• Class-A lab is soon online again. This means e.g. that Faraday-cups can be inspected and repaired again.
• Diagnostic boxes soon to be inspected.
• Balloons will soon be emptied next week, as they are close to being full.

• VISIT: NO sample removal or opening of chambers during visits:
  
  • Director of Nuclear Research at Los Alamos, 11 June, 10:30
  • Polish TV, 11 June. 10:30-12:00.

The next ISOLDE PG meeting will be announced, but will likely be next Wednesday. Followed by the seminar of Janne Pakarinen entitled “Nuclear structure studies in Jyväskylä, Finland”
