14. KEK-B noise experiments

Rogelio Tomas (CERN)

16/12/2010, 08:30

Dedicated beam experiments in KEKB with crab cavities with induced noise to study the impact on beam quality, lifetime and luminosity. The observations of beam-beam instability between the sigma and pi modes and simlations to explain this phenomena is presented. Tolerances based on KEKB measurements for the LHC is derived. The first measurement of crab dispersion using orbit differences with...

10. SPS beam tests with crab cavities

Dr Elias METRAL (CERN)

16/12/2010, 08:50

Feasibility study of KEK-B crab cavities for beam tests in the LHC, infrastructure, cryogenics, collimator configuration and physics objectives for crab cavity tests in the SPS. First results from SPS beam experiments as preparatory steps for a future crab tests in the SPS.

12. Beam simulations for SPS tests

Hyung Jin Kim (FNAL)

16/12/2010, 09:10

Crab cavities are foreseen to be tested in the SPS as a proof of principle before a full implementation in the LHC. Simulated effects of a single crab cavity on the SPS hadron beam, including ideal energy, stable working points, effect of non-zero dispersion, emittance growth and lifetime for crab tests in the SPS. Comparisons to the recent experiments in the SPS for emittance lifetime during...

41. SPS (and LHC) instrumention for crabbed beams

Marek Gasior (CERN)

16/12/2010, 09:30

Available instrumentation in the SPS and LHC to measure signature of crabbed beams, crossing angles in LHC, crab dispersion and head-tail closed orbits. Beam measurements of crab cavity amplitude and phase control using closed orbit distortion, orbit offsets at IP and luminosity measurements, orbit control and feedback near crab cavities and other instrumentation used for crab tests and operation.
