  3. Injector schedule 2012 35 weeks of physics (vs 29 in 2010,2011) Guaranteed protons (46% requested): (Possible increase at next research board) Protons for ISOLDE restart in spring 2014

  4. ISOLDE schedule 2012 Status today: 9 IS experiments and 2 LOIs CLOSED this month 79 IS experiments and 9 LOIs OPEN (711 + 30 requested shifts) + 14 IS experiments and 5 LOIs SUBMITTED to this INTC (193 + 17 requested shifts) 1059 remaining shifts for proposals and LOIs 904+47(LOIs) shifts requested so far (66 more might be still requested) Reasonable number of shifts that can be scheduled in 2012: 590

  5. RILIS operation • Ion beams of 15 elements were produced Laser ON time in 2011: • 2756 h – Total • 2527 h – On-line • > 50 % of the • Total running time of ISOLDE facility • 197 (250) shifts in 2011 • ~ 250 (300) planned for 2012

  6. REX Operation • Delivered shifts for experiments and LOIs in 2011: • REX – 147 shifts (160 shifts scheduled) • Similar plans for 2012: ~200 shifts to be scheduled • Enable 2 ms RF pulse length on all amplifiers for slow extraction tests to be done in 2012 • A few “difficult” light beams will require testing and further tuning

  10. Outline • Status and plans for 2012 experiments • Shifts and schedule • RILIS and REX operation • New experiments for post accelerated beams 2012 • HIE-ISOLDE status and plans • Reports and recommendations from the IAP • Cavity design and tests • Civil engineering and installation work LS1 • Foreseen activities for LS1 • Target area activities • Modifications in the experimental hall • Other plans

  11. Highlights from the IAP report:CryomoduleDesign • The top loading design is a good choice with examples in ISAC-II, LNL, MSU and ANL. • For the cryogenic safety the IAP has the impression that the numbers presented for the burst disk size to mitigate overpressure in the case of a venting accident are over conservative • Concerns about the use of MLI => consider nickel plating of thermal shield and electro-polishing large surfaces (mirror-like) helium reservoir • The cryomodule assembly sequence should be optimized to give adequate access to the cavities in case they have to be rinsed in the future • The capability to helium condition the cavities by adding a leak system to the cryomodule should be analyzed at the cavity testing stage • A 1400 W cryogenic plant should have sufficient margin.

  12. Highlights from the IAP reportRF Cavities • Work on the cavity has made good progress and is on the right path although many cold tests are still necessary to get things settled • It is almost certain that the very stringent specification on the inner conductor beam port is too tight by probably a factor of ten at least. It is suggested that cavity development should proceed with this as a fact while beam simulations are done in parallel to confirm. • It is noted that one of the RF performance curves reaches the high field value 6 MV/m and has a very low Q-slope for a sputtered cavity but a Qo which is a factor of ten from the goal. • evaluate influence of tuner plate

  13. Highlights from the IAP report:General • Possible concerns are related to realities of funding which may cause complicated procurement strategies • Synergies between ESS and HIE-ISOLDE should be explored with regard to the training of people • The goal of having the 5.5 MeV/u linac commissioned in 2014 is tight but still possible => risk analysis by Sep. 2012 • Diagnostics look well thought out and conceptually well advanced for this stage of the project. • Compare safety protocols with other operating facilities • A finalization of the experimental layout is required • The IAP suggests that attention must be given on the production of x-rays • The IAP strongly support the addition of the storage ring to the ISOLDE infrastructure

  14. RF Measurements @ 4.5K (2011)

  15. RF Measurements (2012) ~ 35 W @ 6 MV/m ~ 70 W @ 6 MV/m

  27. Target Area:Robot replacement • The current ISOLDE robots: • are coming to the end of their lifetime. • No compatible spare parts • Are prone to faults • Have no back-up redundancy • Are limited in flexibility • No further programming possible • Part of the long term improvements in operation is to replace the existing robots.

  28. Target Area:Replacement robot • New robot system based on “known” system. Installation in target area – Q4 2013

  29. Target Area: ISOLDE Hot Cell • For the dismantling and oxidation of used ISOLDE targets • Pre-conditioning prior to shipment to PSI for waste treatment Location of new Hot Cell Installation scheduled for long shutdown 2013 Building 179 with target area

  30. Target Area: MedicisMedical Isotopes Collected from ISOLDE • At present 1.4GeV, 2μA p. May have 2GeV, 4-8μA protons in 2018, of which 90% can be recuperated at the dump position. • Samples can be transferred to Class A labs via a pneumatic transport system • "Presentation at ICTR-PHE 2012 conference“ by Thierry STORA

  31. Target Area: Medicis • - Ta(p,X)149Tb is one of the most efficient production method. G. Beyer et al., Radiochim. Acta 90, 247 (2002) • Can use CERN specific technologies for isotope production (i.e. nano-structured target, patent WO2010/034364, CERN) • Large variety of isotopes accessible

  32. Exp. Hall: MINIBALL Move • Beam transfer line • 1 straight section with 2 branches • Oct 2013 – Sept 2014 • MINIBALL move • Oct 2013 – April 2014 • Planning to be discussed in upcoming MINIBALL Collaboration meeting in 2 weeks Miniball Exp. station Actar / Helios Miniball Beam diagnostics

  33. Exp Hall: ISOLTRAP • Mass measurement experiment situated in the middle of the ISOLDE hall • Platform made of wood • Inacceptable for a Class C type laboratory • Plans to re-furbish the platform • Replace wooden platform with an aluminium platform

  34. Exp Hall: RFQ Cooler • RFQ Cooler Alignment check • Laser at limit of transmission for optical cooling experiments • External alignment checks done at the end of 2011 • But to no avail • Internal alignment checks need to be done

  35. PAD & MAD Installation

  36. PAD & MAD Installation • Integration currently under discussion • Limited space in hall (especially near HRS entrance) • Integration in target area • Conflict with hot cell operations • Access difficulties for large equipment (eg. FE’s, BTY magnets)

  37. Buildings 115 & 507 Present situation (ground floor Jura side): Control room

  38. Solid State Lab 115 1. Increasing the surface of the Solid State Lab in B.115: Control room
