Last Week

• Ra-223 and Ra-225 shipping. 
• ThO Target testing and preparation for irradiation / benchmarking for ThO (SCK-CEN) tests.
• Irradiation of TaC for Tb molecular beam collection (MD + Shipping).

 

This Week

• Tb-149 and Tb-155 molecular beam collections. 
  • With delay due to an issue with robot manipulation, was possible to begin collection within 5-6 hours
  • Possibly Tb-149 as difluoride (foil retrieval ongoing)
• Irradiation of ThC for Ra-225
  • Direct from 17-18 (or 19) June #887M
  • Direct with rest of protons from GPS 18-23.06.
• Ra-225 collection for shipment to US

 

Next week

• Tb-155 shipping to Portugal
• Irradiation of ThC for Ra-225
• Ra-225 collection for shipment to US
• New supplier ThC loading (different batch than previously for #887M) and outgassing

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

• Due to the PUMA-ISOLDE project, we must relocate our vacuum controllers (presently located in rack VY.RCX.1, near IDS) in a new mini rack beneath the RC6 beam line., we have to stop the pumping in RCX10 for about three hours

• Mention technical stop and work by EN-CV on the supply plenum

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

Physics

On HRS, the first HIE-ISOLDE run of this year took place. Thanks to the efforts of all technical teams involved, physics at HIE-ISOLDE started already on Thursday, one day earlier than the official start. For the run, ¹⁴⁴Cs beams were sent to Miniball at 4.7 MeV/u to study octupole correlations by measuring lifetimes of excited states. It was the first time that the so-called plunger technique was successfully employed at Miniball. Since on Monday morning, when the run was originally supposed to stop, they had not yet managed to measure new physics, it was agreed that they could continue until Tuesday morning. This allowed them to complete the physics programme, for which they were very grateful.

Schedule

• Yb169 collection doesn’t take place
•  

Summer party: Tuesday 8/7

 

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

Speaker: Oscar Fjeld (CERN)

-Received a request for the new setup of the SPEDE chamber at the IDS station.

-Meeting with safety on Thursday to approve the workshop.

-New cupboard and bandsaw in the workshop.

 

14:55 → 15:00 Safety, AOB, visits

• Proposal for the turnstile and side gate (new stairs), update after previous ITC discussion

• Concerning the sensors we recently added to the HRS magnets, we need to run an Ethernet cable from the acquisition system to an available socket in room R-020.

If there are no objections, we intend first to pull by ourselves a temporary cable along the walls and ceiling. A proper cabling demand will follow as soon as possible.

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)
