Beam Breakup Mitigation by Ion Mobility in Plasma Acceleration

Abstract

Moderate ion mobility provides a source of damping in the plasma wakefield acceleration, which may serve as an effective remedy against the transverse instability of the trailing bunch. Ion mobility in the fields of the driving and trailing bunches is taken into account; the related effects are estimated for the FACET-II parameters.

Effect of the ion mobility in the driver's field is included. Stroboscopic plots of the complex amplitudes are used now. Four pages and four figures
