Outline

Introduction Presentation of the interventions Calendar of the LS1 at ISOLDE Conclusion

Introduction

The long shutdown 1 (LS1) at ISOLDE will enable us to carry out various interventions in the facility Routine interventions Repairs Maintenance Upgrade of the facility

In the target area, labs, class A lab, experimental hall, …

ISOLDE EN, PH, BE, TE LS1 prepared in collaboration with several departments

Presentation of the interventions

Target area (building 838): Handling and transfer of the targets from the target area

to ISR 3 Replacement of the robots Relocation of the services (ventilation, ducts, cooling system, electrical

cables) Repairs of the extraction electrode mecanism Maintenance of the Front-Ends Connection of the High Voltage and radiofrequency

supply BTY pick ups Replacement of the shielded shelves Installation of the RCS (Rail Conveyor System) Proton beam alignment with the SEMGRID target

Presentation of the interventions

Building 179: Post mortem analysis of the target NaF #478 Smear tests on the target BeO #396 Maintenance of the pumpstands PAD/MAD installation Hot cell and RABIT dismantling Civil engineering of the new MEDICIS lab

Experimental hall (building 170): Exchange of the laser windows Work on the lasers RFQ cooler realignment Consolidation of ISOLDE slits HIE ISOLDE works

Laboratories and other activities

Handling and transfer of the targets

Transfer from the target area to the ISR 3 Lowered type A container and remote controlled

pedestrian stacker Done on weekend to limit risks

Positioning of the box containing the targets in the ISR 3

First intervention to reduce the dose rate in the target area

Replacement of the robots

Installation of the shieldings and the cover plates Decrease the dose rate before interventions

> January

• Dismantling of the old robots, rails, cables, robot control room …• Installation of the new rails, robots, … on the ceiling• Installation of a cabling interface box

In collaboration with EN-HE and EN-STI-TCD

Relocation of the services

Assumed by EN-CV et EN-EL

Ventilation ducts, cooling system and cables are in the way of the new rails (GPS side)

Need to modify their layout in order for the new rails to have enough space to be installed

Repairs of the extraction electrode mecanism

Due to a problem on the electrode in 2012 (GPS Front-End)

Possibility to do the same repairs on HRS Front-End as a preventive maintenance

Maintenance of the Front-Ends

Annual preventive maintenance Electrode removal Lubrication Cleaning Visual inspection

Connection of the High Voltage and

radiofrequency supply GPS Front-End

Installation of 2 new cables 1 for high voltage Connect it on an existing

connector 1 for radiofrequency Install a new connector

before connection

In order for the “RF source” targets to be compatible with both GPS and HRS Front-Ends

Intervention made depending on the collective and individual dose

BTY pick ups

Dismantling of the 2 pick-ups Dismantling of one pick-up’s transition

chamber Modification of the electronics, reassembly Vacuum test Reassembly on the BTY line then put under

vacuum

In Building179

Assumed by BE/BI

Replacement of the shielding shelves

Design, build and test a new shelf system dedicated to target storage inside the target area

Micro-switches indicating (in the robot control room) the occupation of each individual shelf space

Modification of the door controls (electrical control, electrovannes put outside to facilitate interventions in case of failure)

In collaboration with BE/OP

Installation of the RCS (Rail Conveyor System)

Preparation of the Faraday Cage HRS Installation of the rails to the dump

RCS can be used for new cameras

Proton beam alignement with the SEMGRID target

Check of the proton beam position on the target once the PS Booster is restarted (16th June 2014)

Corrections of the position if needed

Layout

Building 179: Post mortem analysis of the target NaF #478 Smear tests on the target BeO #396 Maintenance of the pumpstands PAD/MAD installation Hot cell and RABIT dismantling Civil engineering of the new MEDICIS lab

Experimental hall (building 170): Exchange of the laser windows Work on the lasers RFQ cooler realignment Consolidation of ISOLDE slits HIE ISOLDE works

Laboratories and other activities

Post mortem analysis and smear on targets

Post mortem analysis on a target following a short cut Improvement of the next set of targets of the same type Post mortem analysis under a fume cupboard in the

class A lab

Smear on a target Is there any accumulation or a diffusion of isotopes on the surface ? Know the composition Smear under a fume cupboard in the class A lab

Maintenance of the pumpstands

• Performance of the oil pumps decreases throughout the year Changing the oil of the 2 pumps Contaminated oil but no dose rate

Put a special protection cover in order to protect the connections

PAD/MAD installation

Experimental hall (building 170): Exchange of the laser windows Work on the lasers RFQ cooler realignment Consolidation of ISOLDE slits HIE ISOLDE works

Laboratories and other activities

Exchange of the laser windows

Laser ionisation is used for a lot of experiments at Isolde laser passes through a window made of quartz in the separator magnets. Windows become opaque both because of the laser beam and the lost secondary beam

To ensure an efficient laser ionisation windows are replaced each year

In the separator areas (GPS and HRS) Protection of orings from laser light needs to

be integrated

Work on the lasers

Extension of RILIS cabin Modification of the HRS laser window holder

Make an extension tube for mounting the window outside magnet To replace the removal tool

Easy to inspect, easy to replace

RILIS machine protection system GPS laser beam launch New laser for non-resonant ionization New and improved RILIS schemes for the Dual

RILIS system

In charge: BE-OP and EN/STI/LPC

RFQ cooler realignement

RFQ cooler’s internal components are not aligned

Affects the beam transport

Correction of the alignement of the RFQ cooler’s internal components

Checking of the internal electrodes

Calibration of helium buffer gas valve

Consolidation of ISOLDE slits

Electronics of the controller, motors and resolver doesn’t work

Conclusion

LS1 will enable us to upgrade a large part of the facility

Several sections of the EN/STI group and several other departments will work in collaboration in order to manage all the interventions

Collective and individual doses will be reduced as much as possible and estimated thanks to the establishment of WDP 15 WDP under preparation

Safety during operations will be optimized and people will be informed

Thank you for your

attention
