A new technique of correcting emittance dilutions in linear colliders

This article describes a new method of reducing the transverse emittance dilution in linear colliders due to both transverse wakefields and dispersive errors. The technique is a generalization of the dispersion-free [1] correction algorithm; the dilutions are corrected locally by varying the beam trajectory. This technique will complement the BNS damping [2] method which primarily corrects the dilutions resulting from coherent betatron oscillations. Finally, the results of simulations are presented demonstrating the viability of the technique.
