Abstract
A permanent magnet focusing system includes an electron gun that provides an electron ribbon beam having an elliptical shape. A plurality of permanent magnets provide transport for the electron ribbon beam. The permanent magnets produce a non-axisymmetric periodic permanent magnet (PPM) focusing field to allow the electron ribbon beam to be transported in the permanent magnet focusing system.
