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.

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).
