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

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

RILIS operation Ion beams of 15 elements were produced 5 Laser ON time in 2011: Ø 2756 h – Total Ø 2527 h – On-line • > 50 % of the Total running time of ISOLDE facility 197 (250) shifts in 2011 ~ 250 (300) planned for 2012 Beam Sm Ga Mg At Pb Dy Nd Pr Ag Tl Cd Mn Ni Yb Zn Planned 80 104 256 160 184 64 136 - 112 208 288 120 272 - 376 Real 89 101 146 269 221 35 110 4 92 231 242 390 348 73 407

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

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 LS 1 • Foreseen activities for LS 1 • Target area activities • Modifications in the experimental hall • Other plans

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 Me. V/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 xrays • The IAP strongly support the addition of the storage ring to the ISOLDE infrastructure

LS 1 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 – Q 4 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 Building 179 with target area Installation scheduled for long shutdown 2013

Target Area: Medicis Medical Isotopes Collected from ISOLDE • At present 1. 4 Ge. V, 2μA p. May have 2 Ge. V, 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

Target Area: Medicis • - Ta(p, X)149 Tb 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 WO 2010/034364, CERN) • Large variety of isotopes accessible

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

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

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)

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 39

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

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

Building status • Building 115 (extended solid state laboratory) – Plans completed – Costs • 407 k. CHF (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

Target Storage Area 2 new Kuka linear Robots In Isolde Target Area (2013) Handling with 1 remote controlled vehicle Deliver the new target to the exchange point for the Kuka robots Remove hot target and place on the shelf (during shut down) Move the 3 years decayed target from shelf to hot cell Move waste containers (with “standard” trans-pallet) New hot Cell (2013) New Target S. Marzari To PSI

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 LS 1 planning – A few tasks remain to be confirmed – A clear overlap of activities in the target area in Q 4 2013 – A potential conflict between HIE-ISOLDE installation and ISOLDE operation in April 2014.
