Head-Tail Modes for Strong Space Charge

arXiv:0812.3914 · doi:10.1103/PhysRevSTAB.12.044202 10.1103/PhysRevSTAB.12.109901

Abstract

The head-tail modes are described for the space charge tune shift significantly exceeding the synchrotron tune. A general equation for the modes is derived. The spatial shapes of the modes, their frequencies, and coherent growth rates are explored. The Landau damping rates are also found. The suppression of the transverse mode coupling instability by the space charge is explained.
