Electromagnetic Instability of an Intense Beam in a Quadrupole Focusing System

Abstract

Discrete quadrupole focusing systems are subject to the electromagnetic instability previously found in helical quadrupole strong focusing systems. The dispersion relation is derived. Analytical growth rates are obtained. Instability boundaries are established. Numerical solutions of the dispersion relation results show that the overall stability properties are not favorable for long pulse, high-current electron beams.
