      Past and current run : Zn for ISS and Miniball

      • Minor intervention during the week (crystal optimization, dye refill).
      • Everything stable on the weekend until Sunday 01/09/24 at 6:30pm.
      • Called at 6:30 on sunday as the second step (dye laser) was off.
      • After investigation, the power supplier of the pump laser had tripped the fuse in the socket it was plugged in. After restart, the power supplier underwent a series of tiny explosions... 
      • The pump laser was echanged over the night with the replacement one that was in the CRIS lab. Unfortunately, the humidity in the laser was too high to start the spare laser at that point.
      • Fortunately, we found another atomic level from Zn that was close enough to the wavelength for Tm for which one laser was aleady setup. This new scheme was tested and approuved. It gives a bit less than half the yield of the previous one, but this was the only solution at that time.
      • The overall intervention took around 5-6h.
      • Powercut on the 02/03/24 : everything restarted well, and laser reoptimization was performed on the 03/03/24 over lunchtime. 
      • In parralel, the spare laser for dye laser pumping has been brought back to optimal humidity. We will work on its realignment and prepare again the better laser scheme this afternoon.

       

      Future run with LIST:

      • Installation of the LIST equipment in the HT cage. Everything was working fine (coupling, connection, communication, heating...) until the powercut.
      • Checks after the powercut performed on 03/09/24.

      MEDICIS

      Last week 7 MBq of Tb-155 were collected for CHUV. The users are very happy and could proceed with their experiments on the use of Tb-155 for medical imaging.

      848M has been irradiated with 1.2 uA average and reduced number of ppp (2000 max). The vacuum was good and collection went well between Wed and over the week-end. The Ra-224 and Ra-225 samples have been removed on Monday morning for shipping to Mannheim and NPL, respectively.

      This week, on Friday, #807M will go for irradiation over the week-end on the low trolley (0.4 uA average with consigne at 0.5 uA maximum, and ppp max = 1000 ppp).  It will be retrieved on Monday morning for a Tm-165 collection (that will be shipped to Orleans to a PRISMAP user).

      Class A

      n_TOF using R-002 all of tomorrow for putting U-238 samples back in container to prepare for return shipment to JRC

      Schedule

      • Adapted planning for this after power cut

       

      Physics

      - 79Zn miniball run: study of shape coexistence around doubly-magic 78Zn nucleus. The users were grateful to get beam ahead of schedule and, in turn, they agreed to finish 1 day earlier. They managed to collect nice spectra and finish their physics case. They were very impressed with the RILIS intervention on Sunday evening.

      Rack installation in ISS area (no change in footprint)
      “ISS are hoping to replace one of their 19-inch racks with a 19-inch rack that is double the height. The current rack’s location is next to the XT02 beamline. The transport team, safety team, and I have devised a plan to cut the power to the beamline elements nearby (in case a cable becomes exposed), cover the XT02 beamline with tarpaulin (to prevent snagging), rotate the XT02 Earth bar 90˚(for ease of access), and swap the two racks. This will require the use of the crane for 1-2 hours. The footprint of ISS in the hall will not increase as a result, and this procedure should not affect other users.”
