Beam shaping with 4n-order multipole magnets

Folsom, B. LU and Laface, E. LU (2017) 8th International Particle Accelerator Conference, IPAC 2017 In Journal of Physics: Conference Series 874(1).
Abstract

A uniformly irradiating beam is beneficial in spallation for preventing irregular wear on the target. For octupoles (n = 4) and higher-order (n = 4N) magnets, passing charged-particle bunches undergo symmetric shaping effects along the x and y axes. Using a Lie-mapping formalism, we illustrate how well Gaussian distributions can be flattened symmetrically in 2D with single, dual-pulse, and RF magnets of 4N order. Incidental shaping effects are also discussed.
