ISOLDE Frontend Status and Nanolab Richard Catherall ENSTIRBS

ISOLDE Frontend Status and Nanolab Richard Catherall EN-STI-RBS ISOLDE Technical Coordinator ISCC meeting 1 st July 2019

Outline • Frontend Status • Off-line 1 and 2 • Tape station • HT renovation • MEDICIS • Nanolab project • My replacement

Extraction Electrode Design • The feedback from testing the new design on the MEDICIS FE is a concern for the ISOLDE FEs • Bending of the rail, gripping of the bearings, separation of rack from pinion. • Even though operational parameters are not identical • Greater heating power, HT run at a higher vacuum pressure at MEDICIS • Decided to go back to tried and tested version • But this has cost us a lot of time • Overlap of resources for the repair of MEDICIS and FE production

Extraction Electrode Design

Current status • All components and modifications are currently being reviewed. • The objective is to “fix” the design with no more modifications possible. • There is already a 10 month delay in the production of the Frontends. • Every effort will be made to reduce this delay • All pieces for FE#11 are ready so production should be quicker. • Also no more modifications

Offline 1: Maintenance + Upgrades • Removed large control rack and obsolete equipment • Roughing and cooling moved to basement • Beam instrumentation upgraded to ISOLDE type • Maintenance + upgrades of Lab. View control software via LV support -> Increased ergonomics and reliability -> more space for potential new equipment: pump stand, MR-TOF, … Currently: molecular laser breakup studies by target teams and RILIS (S. Wilkins, A. Ringvall-Moberg), then laser system moves to offline 2 Near future: molecular beam formation studies (J. Ballof)

Pump stand upgrades Normally used for target temperature calibration Upgrades: • High-resolution measurement of heating voltages and thermocouples • new Lab. VIEW software for residual gas analyser • Gas system Ongoing: • Automate recording of calibration data • Transition to CERN standard electronic documentation Currently: Extended programme to improve target thermal insulation (V. Samothrakis) Near future: Target material behaviour in the presence of oxygen (S. Stegeman)

New Tapestation Quad FC tape FC Β-det. Final steps in the new fast tapestation project. • It has been a lengthy project, lots of different specialist skills required. • Project stalled due to lack of manpower and other projects of greater importance in 2016 -18. • S. Warren was asked to take over project in July 2018. • Systems must be fully operational start-up 2020 Old Tapestation

Detector commissioning with source July 2018 S. Warren take over Modifications to the detector hardware controls systems with K. Szczurek First radioactive beam tests 124 Cs release-curve measured. Moved to new location at CA 0 Ready for handover to start up and user/ operators. Aug 2018 Sep 2018 Temporary controls software complete and commissioned Nov 2018 Oct 2018 Waiting for beam time First release measurements of 21 Mg ever at ISOLDE t 1/2=122 ms !!!! April 2019 2020 To be completed: • SMB controls crate installation • Vacuum pipes for CA 0 coupling (J. Cruickshank) • SCADA controls for vacuum • Detector optimization in new location. • Final cabling of systems • Tapestation controls software

Work done for the installation of the HT modulators § High precision 60 k. V D. C. HV Power Supply § 2 operational HVPS units installed on HT 1 & HT 2 and 2 spares available. § Target Modulators § § 2 operational HT fast recovery systems installed on HT 1 & HT 2, 1 spare in b 867. Improved HT ripple on HT 1. Measured to < 1 Vpp @30 k. V (to be done on HT 2). Capable of recovery time to 1 Vpp in 1 ms (load dependent but not only…). HV dividers need fine compensation adjustment of the frequency response to truly get precise recovery time < ~ 5 ms. Tested but not yet performed. § FESA 3 compliant control systems deployed § § PXIe controllers and acquisition boards replace the FEC Lynx. OS + GM (discarded). Power Control Units with HT safety interlocks, 1 spare available in b 867. No more water cooling. Only oil circulation pumps integrated in the control. HT 1/HT 2 start modulator triggers auto managed based on the HRS/GPS HT switch position. § On site test load and HT calibration tools for troubleshooting § Dynamic test load for testing HT 1/HT 2 only when disconnected from targets. § External commercial HT divider for DC calibration. § Ripple measurement to 10 -5. § To be done § HT 2 maintenance, fine compensation adjustment of the dividers, cleaning (LS 2). § Old control decabling (YETS 21 -22). § Negative polarity (2021).

General Layout of the Nanolab

Nanolab Projet Progress 2018 2019 2020 2021 • CE works starts Jan 2020 • CV studies and procurement • Process studies and procurement • Start Phase 2 • Préparation Coordination 2021 • Technical infrastructure (DI, Contrôle Accès, EL, RP etc) • Coordination, • Commissioning • Réception de Nanolab Today • Définition du process √ • Design préliminaire du bâtiment et de ses infrastructures techniques √ • Analyse de risque et Safety Review √ • Integration model of all services√ • Civil engineering studies_ finalisation & conforme planning • CE call for tender en cours conforme planning, • Equipment specifications_ en cours, conforme planning, 14

Works coordination_ Phase 1 & Phase 2 : Novembre 2020 -Mai 2021 Phase 1, : January 2020 -October 2020 Overseen by SMB: - Technical corridor to be approved by CV - Final finishing of walls and ceiling including first coat of paint - Passages in walls for services will be done - CV EL Finition SMB (début avec les carottages dans murs existants) IT / DI/ CA/ Gaz Only the SMB group will be responsible during this period E.

179 worksite Phase 1, : January 2020 -October 2020 - Phase 1 Only CE work during this period The 2 exit doors will be blocked during the works. Exceptional opening will be allowed with prior notice. The normal entrance to B 179 will be maintained. No real impact to the users of 179 E. Fontaine 06/06/2019 16

179 worksite Phase 2 : Novembre 2020 - fin Mai 2021 - Ventilation of building 179 will be stopped for 6 months as from December 2020. Impact on actinide targe production and MEDICIS operation. Building connection (Removal of doors) and service connections during this period. E. Fontaine 06/06/2019 17

Evolution of the design since 07/02/2019 v Modification of the buffer area entrance. The CV ducting will be placed in dedicated fire proof compartments. v Reduction in the classification of certain fire proof doors v Retention of water on the roof v The partition between the two labs will not go as far as the concrete roof E. Fontaine 18

Coordination with ISOLDE • Access will be granted for the installation of the Frontends during Phase 1 • Targets will be prepared and completed before the ventilation stop in preparation for 2021 operation. • Will need schedule for start up at least in July/August 2020! • Micro-UC production will remain in 179 -R-001 through out 2021 (except for ventilation stop) • 2021 will be used for commissioning and to validate the nano-material manufacturing procedure. • MEDICIS will not be able to operate for 6 months in 2021
