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

• 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

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

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

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

ISOLDE operation

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.
