18.01.06 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!

18.01.06 PS/SPS days 4

PS internal dumps Goal: 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.

18.01.06 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

18.01.06 PS/SPS days 6

PS internal dumpsFurther 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.

18.01.06 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)

18.01.06 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

18.01.06 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)

18.01.06 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.

18.01.06 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

18.01.06 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).

18.01.06 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.
