  1. SEPTA and spares follow-up J. Borburgh for SEpta section

  2. What is and should be traced in general • Magnetic septa • Complete septa (installed, operational spares, second choice spares) • Operational history (# pulses, failures) • Coils • High current feedthroughs • Lifting jigs (certification) • Electrostatic septa • Complete septa (installed, operational spares, second choice spares) • Operational history (failures) • HV cables • SF6 safety valves for HV generators • Lifting jigs (certification) • Cathodes • HV deflectors • HV feedthroughs • Protection elements • Complete devices (installed, spares)

  3. What is not traced • Magnetic septa • Striplines (consumable) • Electrostatic septa • Feedhtroughs • Protection elements • Absorbing blocks

  4. How and where is it followed-up Depends on operational responsible. Different per accelerator. Different per equipment type (different needs). Mostly documented in Excel files on dfs. Some history on Web pages: AB pages MTF for LHC equipment.

  5. PS complex magnetic elements Operational responsible for LHC back bone: T. Masson • General dfsdirectory: • Operational history per magnet • Pulse history and preventive exchange planning • WDP • Coil inventory • Feedthrough inventory • Lifting equipment • CTF3 and AD equipment less actively followed up

  6. PS complex electrostatic elements Operational responsible A. Prost • Some history on Web pages: • AB pages (obsolete) • Remainder on dfs: • Complete septa (installed, operational spares, second choice spares) • Operational history (failures) • HV cables (not up to date) • SF6 safety valves • Lifting equipment • Cathodes inventory SEH23 • Cathodes inventory SEH31 • Anode foil inventory SEH23 • Anode foil inventory SEH31 • HV deflectors • HV feedthroughs

  7. PS extraction protection elements • TPS15 dummy septum • Operational responsible to be determined • Installed in 2014, spare being validated • No follow up as yet

  8. SPS magnetic elements • Operational responsible: C. Baud • General dfs directory: • Magnet inventory • Water filters • Potentiometer inventory • Complete assemblies, including MS, MP • Coils

  9. SPS electrostatic elements • Operational responsible: B. Balhan • General dfs directory: • ZS inventory • Part inventory (HV component, wires, pot…) • Operational history (Sparks/Failures) • HV cables • Pumping Module with BDI equipment • Intervention, WDP

  10. SPS extraction protection elements Operational responsible B. Pinget • TPST TPSG4 TPSG6 • Global inventory • Spare parts (CC, CFC, Inconel,…) • History

  11. LHC extraction protection elements • Operational responsible: C. Boucly • TCDQ, TCDS, TCDQM, TCLIM …. • Hardware being followed up in MTF

  12. Summary • Main items are already followed up • Presently a very non-homogenous approach For the future tool(s), principal requirements: • ‘Unit’ inventory • History (failure, # pulses, failure history….) • Spare parts inventory (coils, cathodes, yokes, …) • Preventive exchange planning • Safety related items inventory and validation dates (SF6 valves, lifting equipment).
