Particle-in-cell simulations exploring the effects of transverse envel
ope resonances on the emittance of space-charge-dominated beams have b
een carried out using a new 2-D transverse ''slice'' model in the WARP
particle-in-cell code. In this paper, we consider resonances between
an applied quadrupole field error and harmonics of the asymmetric mism
atch mode of beam envelope oscillation. We examine both acceleration a
nd bunching, and show that rapid passage through a major resonance sig
nificantly reduces the attendant emittance growth. Published by Elsevi
