14:05 → 14:10 Operation Report

14:10 → 14:20 REX&HIE ISOLDE

14:20 → 14:30 RILIS

Speakers: Cyril Bernerd (CERN), Katerina Chrysalidis (CERN), Reinhard Heinke (CERN)

 

 RILIS operation from last week : Ca for COLLAPS
- Laser system ready on Tuesday evening and optimized. 
- System stable most of the run, except for a few stabilization problems, but corrected from home or by the users. 
- 2 main interventions on site : 1  dye change and 1 un-related with laser call. 

RILIS setup for the coming week : Sn for HIE ISOLDE

- 2/3 of the laser system was setup in parallel of the Ca run last week. 
- Last laser was setup yesterday. Problem with achieving the wavelength of the first step with the planned laser. Had to change the distribution for the run which took the whole day yesterday. 
- Alignment and optimization performed this morning. Yield check will be done this afternoon for final optimization. 

Other : 

- Blaze switched on by itself last week. No incident to report. It might be because of the interlock with the valve. We need further inspection to check it. 
- Blaze chiller doesn't work anymore. This will be detrimental for the futur run in 2 weeks. We will work on it now that these is ready. If someone if familiar with chiller maintenance, help is welcome. 

14:30 → 14:40 MEDICIS & Building 179

Speakers: Charlotte Duchemin (CERN SY/STI/RBS), Laura Lambert (CERN), Ralf Erik Rossel (CERN)

MEDICIS
Last week, Cu-67 could not be extracted due to bad vacuum in #872M. The vacuum seems to have recover during the week-end allowing for re-use of this target for a next run with UCx that will be dedicated to K-43 collection.
This week, S.Collins from NPL is on-site for collection of Tb. He is especially interested by measuring low activity Tb-149 (4 hours half-life). For now the vacuum in the target is getting better and hopefully a small collection can be done this afternoon to be measured by Sean. Thanks to Ralitsa and Cyril for assistance with MELISSA despite the workload on the ISOLDE side.

BDG 179
Work on the roof should be over end of the week (leak repair).

14:40 → 14:50 Targets, Schedule and Physics

Speakers: Hanne Heylen (CERN), Isabel Frank (CERN), Mia Au, Sebastian Rothe (CERN)

target #865 for COLLAPS Ca

• target performed well, users are happy
• yields were stable until at least Saturday evening (Isa came for yields at 20h) - next check on Monday at 7h30 gave slightly lower yields

target #779 LaCx for ISS Sn

• yields and proton scan
• mass marker heated to 50 A without giving much signal - possibly depleted

target #866 UCx VD5 for Miniball SnS

S injection tests ongoing at offline 1

• new oven design max 50 W, aiming for oven temperatures 200˚C - 300˚C and sufficient cooling by contact with base when target is heated to nominal
• target currently undergoing calibration, to be tested at offline with new S injection 
• original target change as scheduled on Friday

target #867 UCx VD5 for ISS SnS

• under assembly
• target change scheduled for 26th July

target #856 LaCx prototype for ISOLTRAP Cd

• Mo free block design
• test new heat shield design and coupling, aiming ~50˚C delta T
• target change scheduled next Wednesday
• LaC charges under prepatation by Valentina to be finished for loading next week

target #870 LaCx standard MK1 for CRIS Sb 

• target change Aug 1
• back of line heating
• standard temperature profile

14:50 → 14:55 Safety

Speakers: Alexandre Dorsival (CERN), Elodie Aubert (CERN), Nadine Conan (CERN), Simon Mataguez (CERN)

14:55 → 15:00 AOBS, visits....
