  1. PS/SPS Days O. Aberle/ R. Losito for the ATB Group18th January 2006 Restart of the PS/SPS in 2006 Upgrades and repairs on ATB equipment

  2. Overview • Sieve • Internal dumps PS • Beam stoppers • TIDVG (SPS) • Consolidation • Summary PS/SPS days

  3. PS Sieve • 2005 • Sieve dismounted • Mechanical parts replaced (Piston, water and air connections, bearings) • Adjustment of air and water pressure after lab. tests • Sieve re-installed and fully operational • No spare parts, no spare! PS/SPS days

  4. PS internal dumpsGoal: 2 operational (pos. 47,48) + 1 spare 2005 • Transportation shielding problem solved • Dump 48 and spare mechanically refurbished • Cables pulled from B365 to Pos. 47 and 48 • New patch panels produced for old control units and future controls (installation week 8-10) • Water and electrical connectors replaced • Cabling replaced • Capturing magnets checked • Shielded working space (bunker) in B-150 available until end 2006. PS/SPS days

  5. PS internal dumps status • Dump 48 and 47 Operational and fully tested. • Installation: 02/2006 • Spare dump (former dump 47): Operational End 04/2006 • New power supplies (thanks to PO) ready and tested PS/SPS days

  6. PS internal dumps Further work: • Develop PLC based new control units (ATB/LPE) • Replacement of the control units during shutdown 06/07 ATB-LPE • Design and production (2007) of new supports to simplify the alignment procedure • Installation of new bunker in 867 (2007) • Proposition: Delay the production of the second chariot (consolidation) to 2007. PS/SPS days

  7. PS beam stoppers • 30 stopper (~ 5 types) in the PS complex • Stoppers mechanics in acceptable conditions • Annual maintenance of installed units • Electrical and pneumatic connections have to be replaced (2006-2009) • New stopper positions required • Using revised spare stoppers • New spares have to be produced (2008) PS/SPS days

  8. SPS TIDVG (internal SPS dump)Goal: 1 operational + 1 spare • Historic: • 5 Ti foils stretched over dump core material to prevent contamination by graphite dust • Observation: foils were deformed and lifted resulting in aperture limitation! Ti-foils were removed in 2005 PS/SPS days

  9. SPS TIDVG 2005 actions • Removal of Ti foils by cutting with special tool on spare TIDVG was not successful • Opening of the core by cutting the EB welds in the central workshop • Remove and recondition all absorbing blocks • On graphite blocks: • Removal of old Ti coating • CO2 blasting • Heat treatment • Ti re-coating • Assembly, machining (CERN) and EB welding (Techmeta) PS/SPS days

  10. SPS TIDVG 2006 • Installation of modified unit in February 2006 To be done in 2006 • Store the damaged TIDVG as back up • Modification of spare core • Modify the spare cast iron body (TED type) to get a full spare TIDVG • Assemble the spare core, weld it and fit it into the transformed shielding. PS/SPS days

  11. Consolidation project on beam intercepting devices • ~250 objects from BDI/BT and other orphans (e.g. stripper) with beam intercepting but no instrumentation functions • To be analyzed one by one (all machines) • documentation to be gathered • functionality to be understood, • limitations to be evaluated in view of the new beams • Needs for maintenance and priorities • Budgets to be allocated • Maintenance to be scheduled • Interventions on break until end of consolidation project (3-4 years) • Consolidation program to be launched 15 FTE and 3 Mio CHF during the next three years (in addition to the existing capacities or after 2008) • Standardization and upgrade solutions to be studied and planned PS/SPS days

  12. Strategy until completion of consolidation • ATB and BDI commonly ensure the follow up until full transfer of know-how • ATB-TD Mechanics & ATB-LPE Electronics : • Transfer line objects were partly produced by TD, their controls are being analyzed, manpower (1 technician LPE) will be available in March 2006 • Accelerator components: staff not included in the staff plan. Very dependant on future resources (start of consolidation project). PS/SPS days

  13. Summary • PS Dumps: Two upgraded dumps plus 1 spare ready for startup 2006. New electronics ready for shutdown 2006/07. • PS sieve: Existing sieve upgraded, construction of a spare not before 2007. • PS beam stoppers: Inventory and annual maintenance, revision of beam stoppers East hall. • TIDVG: One dump ready for start up. Preparation of spare in 2006. • Integration of ~250 objects during the next 3 years rely on a consolidation project. The staff situation should improve after completion of CNGS. PS/SPS days
