“Correction of sextupole misalignments (+ FCC-ee collider optics)”
The misalignment of sextupole magnets gives the most stringent condition to achieve a small vertical emittance in an electron storage ring or a collider.
This talk will present a possibility to correct the misalignment looking at turn-by-turn measurements of x-y coupling and dispersion by BPMs, then feedback to skew quadrupole correction winding on the sextupoles by reverting an analytic response matrix.
If it is applied to the FCC-ee ring, the resulting vertical emittance will be below the requirement, under a very loose resolution of the BPM, around 200 um/shot.
