      CERN matters

      Budget and administration: NMS, travel and conferences, absences

      Technical
      - Gas bottles -> make sure you pick up the gas bottles you've ordered and send back empty bottles
      - Chilled water will be stopped since load is necessary -> see e-mail Erwin
      - Vacuum pumping setup: Do not start pumping while connected to exhaust (if you are doing it already, no issue), you can disconnect from the exhaust line and pump into the hall directly but need to place an oil mist filter (also for non-oil pumps). Contact RP to check if pumping without exhaust is ok for you setup. If not, pumping is not permitted until mid-April.
      - Electrical habilitation

      • CM1 transport timeline shifted to April - SAS and area around buffer zone free by Friday 11th of April
      • Dismantling of RILIS moved forward starting 30th of March
      • Road closure route Rutherford next to b. 133 for at least 1 month starting Monday 16/3. That day, conveniently, also route Democrite will be closed.

      For week 16 a lot of handling up and around the REX/HIE tunnel is to be expected and even when on the more detailed planning it is concentrated around the 14th and 15th April there will be actions that run out or preparational work. Opening and closing the tunnel roof isn’t an easy job and apart from necessary dewar handling the crane should stay dedicated to only the tasks related to the HIE tunnel roof and CM1 handling in the hall.

      By the second half of week 16 (16/17 April) the Cryo Module will be standing next to the yellow RP buffer zone close to the SAS and it will be equipped with vibration and tilt sensors to monitor the transport to SM18 and it will be wrapped thoroughly to withstand possible bad weather conditions. We are expecting from the transport company and the authorities (border and road closure) that they will prefer the Thursday or Friday 23/24 April for the actual transport of CM1 to SM18. To be confirmed.

      It means that the handling zone in front of the SAS / RP buffer zone becomes a delicate area from ~ 14 – 24 April.

      Also the SAS will need to be almost empty during week 16 to be able to get the various lifting tools and machinery in and out and especially during the transport day when the special trailer is driven backwards into the hall (fits within 1-2cm with regard to the XT03 dipole blocks..) the SAS needs to be completely empty (meaning nothing on the floor, the shelfs are staying but everything else needs to be moved into the hall or outside.

      Title: The transformation of TRIUMF’s radioactive ion beam facility - additional target stations and ion sources
      Speaker: Jens Lassen (TRIUMF)
      Abstract: TRIUMF is currently undergoing a long 2026 shutdown, to resume the radioactive ion beam program in the isotope separator and accelerator facility, with additional target stations and ion sources. This will allow to deliver multiple radioactive ion beams to different experiments simultaneously.
      In addition to one additional proton target station with an ISOLDE style hermetically sealed target, designed to accept up to 100uA continuous proton beam, a similar target station for photofission with up to 10mA 30MeV electron beam on a converter target will be installed, to provide a different isotope production spectrum. Beams from these target stations will be separated by a low resolution mass separator (R=300). One of these beams can be further separated by a high throughput isobar separator to provide clean RIB’s to experiments.
      Each of these target stations will be equipped with an independent resonant ionization laser ion source based on titanium sapphire lasers. FEBIAD type ion sources will have to be adapted and optimized to the new target ion source systems.
      The presentation will touch upon current capabilities and the upgrades which are scheduled for comissioning starting in the summer of 2027.
