Abstract

The charged-particle beam system includes a non-axisymmetric diode forms a non-axisymmetric beam having an elliptic cross-section. A focusing element utilizes a magnetic field for focusing and transporting the non-axisymmetric beam, wherein the non-axisymmetric beam is approximately matched with the channel of the focusing element.
