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

5 BeamSmGaMgAtPbDyNdPrAgTlCdMnNiYbZn Planned Real RILIS operation  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 Laser ON time in 2011: Ion beams of 15 elements were produced

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

Highlights from the IAP report: Cryomodule Design 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.

Highlights from the IAP report RF 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

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 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

LS1 Activities for ISOLDE Robot replacement Hot Cell Installation Medicis Target storage area Miniball move ISOLTRAP platform RFQ Cooler alignment HIE-ISOLDE PAD-MAD installation – Building 115 move/installation – Building 507 (light building) Target Area Experimental Area

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.

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

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

Target Area: Medicis Medical 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

- 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 Target Area: Medicis

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

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

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)

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

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

40 Replace building 507 Control room 2. Replacing the existing building 507 by a new building - Ground floor (only accessible from within the surveyed area):

41 Control room 2. Replacing the existing building 507 by a new building - First floor (accessible from outside the surveyed area): Replace building 507

Building status Building 115 (extended solid state laboratory) – Plans completed – Costs 407kCHF (to be secured) – Make building 275 available for other users – Implies all handling of radioactive sources to within the confines of the ISOLDE perimeter Building 507 (light building) – Under discussion – HIE-ISOLDE data acquisition rooms outside hall – Visitor’s room – access to visitors will be denied in future when the hall will be defined as a controlled area. – A new version being considered based on partly metallic structure and partly “portacabin” type modules

Summary Operations 2012 – A busy year ahead with a little more planned due to the extended operation time. – The shift backlog clearly indicates the growing demand for physics at ISOLDE HIE-ISOLDE – Moving out of the R&D phase and into the procurement phase. – Important milestones to attain in 2012 to maintain the current schedule ISOLDE LS1 planning – A few tasks remain to be confirmed – A clear overlap of activities in the target area in Q – A potential conflict between HIE-ISOLDE installation and ISOLDE operation in April 2014.
