This web coordinates the hardware (re-)commissioning (HWC) of the existing and future FAIR accelerator facility. The term 'hardware commissioning' covers the following two aspects:

Initial hardware acceptance tests

• Checks conformity with contractual design targets
• Done once, or after major upgrade or modifications
  • mainly done by system responsible/experts
  • coordinated by existing project structure and machine project leaders (i.e. not FC2WG)
    • FATs - Factory-Acceptance-Tests
    • SATs - Site-Acceptance-Tests

'Dry-Runs' & 'Machine Checkout'

• main aim:
  • Checks conformity of system's controls integration and readiness for Commissioning with Beam
  • check as much control/system functionality without beam as possible
  • Machine is put into a state assuming that beam could be injected into the ring/segment
    • unavailable devices/systems are at first ignored, noted down, and followed-up at a defined later stage

A note on terminology:

• Dry-runs: a rehearsal of the accelerator performance/function, starting typically six month before the targeted real Commissioning with Beam
  • needs to (partially) repeated after shut-down or longer technical stop with substantial modifications (e.g. re-cabling, opening of cryogenic, …)
  • initial frequency: 1-2 days every month
  • frequency increased depending on the outcome of the initial dry-run tests
• Machine Checkout: intense accelerator performance tests (e.g. machine patrols, magnet/PC heat runs, etc.), starting typically two weeks before the targeted Commissioning with Beam)
  • needs to repeated after every shut-down or longer technical stop
  • repeated also on the long-term during routine operation of existing accelerators (already existing procedures/usus for existing machines)
