      Last Week

      • Shipping of Ra-225 to CMI Czech Republic
      • Collection of Eu-145 for NPL
        • Collected 5 MBq - Good for shipment
      • Intervention on monday at MEDICIS separator rack to remove the Pin 7 direct connection.
        • Thanks to Julien Parra-Lopez for help
      • K-43 development run Friday-monday 
        • 5.5 % Efficiency (low)
        • UCx Target vacuum limitations - still to be investigated. MM return on Pin-8

       

      This Week

      • Shipping:
        • Ra-225 to KUL, Belgium
        • Eu-145 to NPL, UK
      • Cu-67 development run Today
        • Strong laser effect observed and collecting Cu-67
        • Cu-63/65/67 beams observed already at ~1100 oC.
        • Target vacuum limitations. 
      • Direct irradiation of TaC VD-5 target until Wednesday 20th 9:00
      • Tb-149/155 development run from Wednesday 20th august 9:00
        • Important to begin as soon as protons are stopped
      • Ra/Ac-225 radiochemical separation development

       

      Next week

        • Tb-155 run continued
        • Cu-67 development run from a different (ISOLDE) UCx target.
          • Mass marker on pin 7 but return on pin 2.
          • Lasers needed
          • Goal - max efficiency to prepare for shipment in September.
        • Preparation for the Yb-175 ampoule reception from ILL and transfer
          • Cold test towards the end of the week.
    • 14:40 → 14:50
      Targets, Schedule and Physics 10m
      Speakers: Hanne Heylen (CERN), Isabel Frank (CERN), Matthias Alexander Grasser, Simon Thomas Stegemann (CERN)

      Physics

      On GPS, post-accelerated 94Kr beams were sent to ISS to study the onset of deformation towards N = 60 via transfer reactions. While the yield was a factor of 3 lower than expected, nature helped a bit by having a larger reaction cross section than predicted, so the experiment remained feasible. Unfortunately, on Sunday morning, the target failed, stopping the run 2 days earlier than foreseen. Nevertheless, a relatively good spectrum could be obtained and the users are not unhappy. They continued with stable Xe from the EBIS which will still allow to get them some new physics, and they will run in this mode until Wednesday.

      Schedule

      • Please inform me in case of a major issue (during working hours or outside of working hours)
      • As discussed at the FOM this morning, a source valve of Linac4 has to be exchanged, which will take of the order of 12 hours total, including recovery time. Our proposal is to stop the beam tomorrow, Wednesday 19th of August, at 7h30, with machine accesses starting at 8am. Beam will hopefully be back in the early evening.
        • Affects planned proton scan and yield checks
      • 2.5 uA TBD
      • RaF after the stop of protons update
      • Requested to add a collection during IS715 9-15 September for calibration source:
        • 207Bi (~4h of beam implantation for activity~1e4 decays/s). 
          Potential contaminants: 207At
          - 137Cs (~4h of beam implantation for activity~1e4 decays/s). 
          Potential contaminants: 137I
          - 134Cs (~3h of beam implantation for activity~1e5 decays/s). 
          Potential contaminants: 134La, 134I
          - 133Ba (~1.5h of beam implantation for activity~1e4 decays/s). 
          Potential contaminants: 133La, 133mBa, 133I

          Important to note: All of them require beam intensities above 1e9 
          ions/sec to be implanted in a reasonable time.
