SEPTA and spares follow-up

SEPTA and spares follow-upJ. Borburgh for SEpta section

What is and should be traced in general

• Magnetic septaComplete septa (installed, operational spares, second choice spares)Operational history (# pulses, failures)CoilsHigh current feedthroughsLifting jigs (certification)

• Electrostatic septaComplete septa (installed, operational spares, second choice spares)Operational history (failures)HV cablesSF6 safety valves for HV generatorsLifting jigs (certification)CathodesHV deflectorsHV feedthroughs

• Protection elementsComplete devices (installed, spares)

What is not traced

• Magnetic septaStriplines (consumable)

• Electrostatic septa Feedhtroughs

• Protection elementsAbsorbing blocks

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 pagesMTF for LHC equipment.

PS complex magnetic elements

Operational responsible for LHC back bone: T. Masson• General dfs directory:

Operational history per magnetPulse history and preventive exchange planningWDPCoil inventoryFeedthrough inventoryLifting equipment

CTF3 and AD equipment less actively followed up

PS complex electrostatic elementsOperational responsible A. Prost• Some history on Web pages:

PS extraction protection elements

• TPS15 dummy septum– Operational responsible to be determined– Installed in 2014, spare being validated– No follow up as yet

SPS magnetic elements

• Operational responsible: C. Baud• General dfs directory:

Magnet inventoryWater filtersPotentiometer inventoryComplete assemblies, including MS, MPCoils

SPS electrostatic elements

• Operational responsible: B. Balhan• General dfs directory:

ZS inventoryPart inventory (HV component, wires, pot…)Operational history (Sparks/Failures)HV cables Pumping Module with BDI equipmentIntervention, WDP

SPS extraction protection elements

Operational responsible B. Pinget• TPST TPSG4 TPSG6– Global inventory– Spare parts (CC, CFC, Inconel,…)– History

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

SummaryMain items are already followed upPresently 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).
