Beam based alignment at LEP

We describe a beam-based method for finding the relative offset between beam position monitors (BPMs) and the magnetic centres of the adjacent quadrupole magnets. The strength of a given quadrupole is modulated and the induced closed orbit oscillation measured for different beam positions, reaching...

description We describe a beam-based method for finding the relative offset between beam position monitors (BPMs) and the magnetic centres of the adjacent quadrupole magnets. The strength of a given quadrupole is modulated and the induced closed orbit oscillation measured for different beam positions, reaching a minimum when the beam is centred in the quadrupole. The BPM reading at this point is a measure of its offset, which may be determined at LEP with an accuracy of ~40x10-6 m.
