Intrabeam Scattering in the NLC Main Damping Rings

Abstract

This note documents a set of expressions used to explore the issue of whether or not it is reasonable to consider a conventional positron source for a Tesla formatted beam. The critical issue is that of energy deposition in the conversion target and the comparison of the induced stress with the ultimate tensile strength of the target material. Since the length of the incident beam pulse is large in comparison to the ratio of beam size to the speed of sound, the concurrent pressure pulse dissipates in a time short compared to the overall pulse duration and one is left with only the

Low emittance lattice for the storage ring of the Turkish Light Source Facility TURKAY

“…One of the important nonlinearity issues for a low emittance storage ring is intrabeam scattering, which is the Coulomb scattering within a beam, which usually increases the beam emittance. The horizontal beam emittance and relative energy spread with intrabeam scattering are [14,15]…”
