  1. Interventions for LS1 EN-STI Group meeting 1st February 2013 Elodie Macario EN/STI

  2. Outline • Introduction • Presentation of the interventions • Calendar of the LS1 at ISOLDE • Conclusion

  3. Introduction • The long shutdown 1 (LS1) at ISOLDE will enable us to carry out various interventions in the facility • Routineinterventions • 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

  4. Presentation of the interventions • Target area (building 838): • Handling and transfer of the targetsfrom the target area to ISR 3 • Replacement of the robots  Relocation of the services (ventilation, ducts, cooling system, electrical cables) • Repairs of theextraction electrodemecanism • Maintenance of the Front-Ends • Connection of the High Voltage and radiofrequency supply • BTY pickups • Replacement of the shieldedshelves • Installation of the RCS (Rail Conveyor System) • Proton beamalignmentwith the SEMGRID target

  5. Presentation of the interventions • Building 179: • Post mortem analysisof the targetNaF #478 • Smeartests on the targetBeO #396 • Maintenance of the pumpstands • PAD/MAD installation • Hot celland RABITdismantling • Civil engineering of the new MEDICIS lab • Experimental hall (building 170): • Exchange of the laser windows • Work on the lasers • RFQ coolerrealignment • Consolidation of ISOLDE slits • HIE ISOLDE works • Laboratories and other activities

  6. Handling and transfer of the targets • Transfer from the target areato 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

  7. Replacement of the robots • Installation of the shieldings and the cover plates  Decrease the dose rate before interventions • 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 > January In collaboration with EN-HE and EN-STI-TCD

  8. Relocation of the services • Ventilation ducts, cooling system and cablesare 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 Assumed by EN-CV et EN-EL

  9. Repairs of the extraction electrodemecanism • Due to a problem on the electrode in 2012 (GPS Front-End) • Possibility to do the samerepairs on HRS Front-End as a preventive maintenance

  10. Maintenance of the Front-Ends • Annual preventive maintenance • Electrode removal • Lubrication • Cleaning • Visual inspection

  11. 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

  12. BTY pickups • 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

  13. Replacement of the shieldingshelves • Design, build and test a new shelf system dedicated to target storage inside the target area • Micro-switchesindicating (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

  14. 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

  15. Proton beam alignement with the SEMGRID target • Check of the proton beamposition on the target once the PS Booster isrestarted (16thJune 2014) • Corrections of the position if needed

  16. Layout • Building 179: • Post mortem analysisof the targetNaF #478 • Smear tests on the targetBeO #396 • Maintenance of the pumpstands • PAD/MAD installation • Hot celland RABITdismantling • Civil engineering of the new MEDICIS lab • Experimental hall (building 170): • Exchange of the laser windows • Work on the lasers • RFQ coolerrealignment • Consolidation of ISOLDE slits • HIE ISOLDE works • Laboratories and other activities

  17. Post mortem analysis and smear on targets • Post mortem analysis on a target following a short cut  Improvement of the next set of targetsof the same type • Post mortem analysis under a fume cupboard in the class A lab • Smear on a target  Is thereanyaccumulation or a diffusion of isotopes on the surface ?  Know the composition • Smear under a fume cupboard in the class A lab

  18. Maintenance of the pumpstands • Performance of the oil pumps decreases throughout the year • Changing the oilof the 2 pumps • Contaminated oil but no dose rate • Put a special protection coverin order to protect the connections

  19. PAD/MAD installation PAD MMAD MAD KEYS CHECK POINT RP In charge: GS-ASE-SSE

  20. Hot cell and RABIT dismantling • Current RABIT will be replaced by a new one, dedicated to CERN-MEDICIS • Current hot cell will be replaced by a new one enabling the dismantling of actinide targets

  21. Civil engineering of the new MEDICIS lab Recuperation of dumped protons for the production of medical isotopes New target storage Mass separator New hot cell RCS Buffer area

  22. Layout • Building 179: • Post mortem analysis of the targetNaF #478 • Smear on the targetBeO #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 coolerrealignment • Consolidation of ISOLDE slits • HIE ISOLDE works • Laboratories and other activities

  23. Exchange of the laser windows • Laser ionisation isused for a lot of experimentsat Isolde  laser passes through a windowmade of quartz in the separatormagnets. Windows becomeopaquebothbecause of the laser beam and the lostsecondarybeam • To ensure an efficient laser ionisation  windows are replacedeachyear • In the separator areas (GPS and HRS) • Protection of oringsfrom laser light needs to be integrated

  24. 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

  25. RFQ coolerrealignement • RFQ cooler’sinternalcomponents are not aligned  Affects the beam transport • Correction of the alignement of the RFQ cooler’sinternal components • Checking of the internal electrodes • Calibration of helium buffer gas valve

  26. Consolidation of ISOLDE slits • Electronics of the controller, motors and resolver doesn’t work • Fabrication • Removal of the pieces of equipment • Replacement In collaboration with: EN/STI/ECE

  27. HIE ISOLDE works We are involved in : • Upgrade of the demineralized water system • Cabling • Safety system installation • Arcon  RAMSES • Fire detection • Start of the cryogenic system installation • Services, magnets and beam diagnostic installation • Linac tunnel installation

  28.

  32. 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
