BeamBeam
• Pilot Beam for the most part:Pilot Beam for the most part: Single bunch Intensity: 5 - 10 x 109 protons per bunch Clear aim to minimise losses and use beam sparingly when
we know where it’s going.
• Total intensity: 4 x 10Total intensity: 4 x 101313 protons protons Over 2 weeks Comparable with one nominal intensity LHC extraction from
the SPS

IntegrationIntegration• Integration: full-blown system wide integration test.Integration: full-blown system wide integration test.
Field test beam related equipment and instrumentation Power converters, kickers, septa, dumps, instrumentation,
synchronisation, timing, RF, beam interlocks With cryogenics, QPS, interlocks
and get them all working together Stress test controls infrastructure and all that goes with it. Fully validate integration
The lessons learnt will undoubtedly speed full commissioning
