Description
Orbit correction is a fundamental feedback action that is applied to the beam in
order to counteract disturbances due to misalignments, ground motion, dynamics
effects, etc. Threading the very first LHC pilot beam though the 26.7 km ring relies
on the ability to properly correct the beam trajectory. The requirements for orbit
correction on transfer functions and hysteresis of the LHC orbit corrector magnets
will be presented and compared to the first magnetic measurement results. The
requirements will be presented both for manual corrections by the operators and for
real-time corrections by a feedback system.
