- Particle losses and emittance growth in the injection process can result from mismatched injected beams arising from quadrupole errors in the ring and injection line. We describe a method, based on carefully analyzing the BPM-corrector response matrix, wh

Crude scaling laws for the dynamic aperture of LHC from random non-linear errors

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- We discuss scaling laws for the dynamic aperture with respect to number of random multipoles in the machine, strength of the multipoles, and multipolarity-flavor n. Moreover we find rules of thumb for the combined effect of multipoles with different n on

Measuring Hamiltonian coefficients with a wobbling method

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- We propose a method to determine the coefficients of the hamiltonian that represents the cumulative effect of all sextupoles in a circular accelerator. The method is based on the low-frequency sinusoidal excitation of orbit corrector magnets and detecting
