Description

High intensity and high brightness beams in FCC pose significant challenges due to coherent instabilities and beam collimation. Usual ways to control the instabilities, such as nonlinear octupole magnets, beam feedback dampers, employment of chromatic effects as well as standard types of the "hard-material" collimators become less effective at the ultimate FCC-hh beam paramters. We briefly present two applications electron lenses which utilize space-charge forces of low-energy, magnetically stabilized electron beams: 1) a novel method to provide sufficient Landau damping in the particle beams ; and 2) hollow electron beam collimation. The proposed methods are free of operational limitations, cost effective and show great promise for the FCC-hh.
