Last Week

• MD for MEDICIS separator gas system software
• Target testing and outgassing pre-irradiation/preparation
• TiC irradiated sample isotope release studies
• Opening of the collection chamber shielding for diagnostic box (S. Marzari)
• Intervention in MEDICIS bunker by BI
• ThC target #848M indirect irradiation for collection and shipping 2.15E+18 PoT

 

This Week

• Ra-223 and possibly Ra-224/225 collection 
  • Shipment to Rennes and Czech Republic
• Irradiated TiC isotope release studies
• ThC target direct irradiation - was foreseen on Thursday, but might be affected by the KUKA robot issues and already changed target on HRS.
  • Initially was intended for MD, but will need to be allocated for Ra-225 collection for shipment to Czech.

 

Next week

• Ra-223 and Ra-225 shipping. 
• Target testing and preparation for irradiations.
• Indirect irradiation of TaC for Tb molecular beam collection (MD + Shipping).

5 Targets, Schedule and Physics

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

Physics

• On the HRS, neutron-rich argon beams were delivered to CRIS for laser spectroscopic investigations of nuclear structure in the region around N = 28. Up until Sunday, the run was progressing well, with new data successfully collected for several isotopes, and prospects were promising to achieve the physics goals by the planned end of the run on Thursday. However, due to issues with the proton beam on Sunday, followed by problems during the GPS target change on Monday, the experiment had to be prematurely stopped. As a result, several isotopes, particularly the most exotic ones, are left with insufficient statistics.
