Minutes from ISOLDE Physics Group meeting, 25th November 2015.

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

Technical news:

No more protons for ISOLDE until next year.

GPS:
- Target was installed for the separator courses.
- Target change was problematic. A now recurrent yet intermittent problem of being unable to open the target Faraday cage (closing the cage this time was no problem).
  - The TELEMAX needed to be used, and the cage was opened.
  - High priority to fix the cage door. “Good timing” of the problem as we enter the shutdown, where the problem will be investigated and fixed.
HRS:
- The proton irradiated (activated) target from MEDICIS is now mounted cold in HRS.
RILIS:
- Testing new laser schemes on the activated MEDICIS target on the HRS, without heating.
  - Non-successful, as they got too low efficiency. They wanted to make tests for Radon/Neon.
- A new laser has arrived which is being setup. This will be used for future Se, Cr, Gd, …
HIE:
- Before shut down a max full power at 6 mV/meter test was performed for 1 h with success.
- The Cryo-module is now warming up for the planned removal.

MINIBALL: Installed and tested a new sensitive electron spectroscopy detector (SPEDE) using stable beams.
- They had many investigations and optimisations.
- The SPEDE detector could only tolerate 1/3 of the powering up, as it started to oscillate due to noise.
- All in all a valuable learning process. The setup will most likely go back to Finland where modifications will be made.
Test of HIE beam line 2, XT02:
- The line had the first official commissioning of beam (1-2 h of stable 12-C and 14-N) on the chamber.
  - Success and transmission looks promising.

The fence for the work zone is back (removal of the Cryo-module/tunnel). Limit your use of the zone and enter with helmet and closed shoes. Close the fence if open.
LN2 exchange of dewars after 17:00 when possible.
The card reader for the ISOLDE Jura entrance of building 170 has been removed.
Dosimeter access for the 508 controlled area (bottom floor) is in place and working.

Kitchen installation is on going.
The new ISOLDE control room is being setup.
New meeting table in the visitor’s area.
Door handles have been fixed, but the door to ground floor controlled areas is still hard.
Please keep the area below stair case empty and clean.
- There are some wooden boxes that have to be removed.

Contaminated pieces are in the process to be dismounted and moved for safe storage or more likely disposed.

Many visits this year – a record!
The statistics from Kara: 2014: 742 visitors and 2015: 840 visitors!
- A big thanks to Kara, and the volunteers/guides/presenters helping out.
Maria plans to make a Video (max 10 min. length) of the ISOLDE hall and its experiments.
- Be ready with a short script/presentation of your experiment at the beginning of next year. Before April.
- Label your experiment in the Hall – try to use a common font/design. Action during Jan/Feb.

The ISOLDE Workshop will start next week.
- Please, the students should help out as much as possible during the workshop and for preparations.
A photo carousel will likely be made for the last day of the workshop (Friday).
- If you have pictures you want to share they can be sent to Jenny.

There will be no ISOLDE PG meeting next Wednesday, due to the ISOLDE Workshop 2015.
