Abstract

It is shown that intense corkscrewing and periodic wobbling elliptic beam equilibria exist in piecewise uniform magnetic fields. The envelope stability analysis reveals that the corkscrewing elliptic beams in a uniform magnetic field are stable, whereas the periodic wobbling elliptic beams are stable in certain regions in the parameter space. These results are useful not only in beam matching, but also in producing large-aspect-ratio sheet beams for high energy accelerators such as the Next Linear Collider as well as for use in high-power rf sources such as sheet-beam klystrons
