Last Week

• #880M preparation with ThC charge for indirect irradiation over Easter holidays and weekend

 

This Week

• #887M preparation with fresh batch of ThC charge for of indirect irradiation over weekend
  • Quick test on MEDICIS FE before irradiation
• Ra-224/225 double collection from #880M ThC. 
  • Recieved 3.89E+18 PoT (indirect)
• Preparation of the pumpstand for the release studies (target change)
• Radiochemical separation on collected Tb-155
• Preparation of #899M VD-5 TaC in anticipation for irradiation on 1st of May.

 

Next week

• Ra-224/225 double collection from #880M ThC. 
• Ra-224/225 double collection from #887M ThC. 
• Irradiation of #899M VD-5 TaC (direct) on 1st of May. TBC
• Irradiate TaC samples for release studies (tuesday-wednesday 29-30).

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

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

Physics

• On HRS, the WISArD experiment used a 32Ar beam to study beta-delayed proton emission, aiming for precision measurements of the weak interaction in the search for physics beyond the Standard Model. The experiment faced challenges on multiple fronts and will likely achieve approximately only one third of the originally hoped statistics (to do as well as last year)
• ISOLTRAP has safety clearance already, ready to start whenever they get beam :-)

 

Schedule

Current status

• No parallel GLM/IDS operation beginning of May 
• No IS715/LOI281 on GLM in May but IS715 continues on LA1
• No Cd beam time in june
