RILIS operation
2756 h – Total 2527 h – On-line
• > 50 % of the Total running time of ISOLDE facility197 (250) shifts in 2011~ 250 (300) planned for 2012
Laser ON timein 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

Outline• Status and plans for 2012 experiments

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 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
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

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: 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
• - 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
• 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

Exp. Hall: MINIBALL Move
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)

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 Q4 2013– A potential conflict between HIE-ISOLDE installation and ISOLDE
operation in April 2014.
