Dielectric guide for electron beam transport

A dielectric guide for transporting an electron beam comprising:

• (a) an enclosure defining a cylindrical cavity adapted to have an electron beam injected therein, said cavity having a diameter/length aspect ratio of approximately 1.5;
• and
• (b) a sheet of dielectric material disposed within said cavity for interaction with the electron beam injected into said cavity, said dielectric material interacting with said electron beam and establishing a focusing action for guiding the electron beam through said enclosure.

A dielectric guide for transporting an electron beam comprising:

• (a) an enclosure defining a cylindrical cavity adapted to have an electron beam injected therein;
• and
• (b) a sheet of dielectric material disposed within said cavity for interaction with the electron beam injected into said cavity, said sheet of dielectric material has a dielectric thickness in the range of 0.1 to 10.0 miligrams per square centimeter, said sheet mounted in a plane which is in perpendicular relationship with a longitudinal axis of said cavity, said dielectric material interacting with said electron beam and establishing a focusing action for guiding the electron beam through said enclosure.
