Accumulation and Ramping in the LHC

Changes in the multipole errors of the superconductingmagnets in the LHC affect important beamparameters such as tune, coupling and chromaticity. Inthe following we estimate the resulting changes in thebeam parameters for the expected magnet errors duringbeam accumulation and ramp, and identify erro...

Sumario:Changes in the multipole errors of the superconductingmagnets in the LHC affect important beamparameters such as tune, coupling and chromaticity. Inthe following we estimate the resulting changes in thebeam parameters for the expected magnet errors duringbeam accumulation and ramp, and identify errorcomponents which require a dedicated compensation ofthe time dependent effects.
