1. A device useful in generating X-ray radiation, comprising:
- a housing including at least one port for at least partially evacuating the housing of atmosphere, at least a portion of the housing being substantially transparent to X-ray radiation;
a first object comprising a first material within the housing, the first material comprising a metal; and
a second material within the housing, the second material comprising a polymeric insulator insulated from ground;
at least portions of the first object or at least portions of the second material moveable relative to the other so as to produce a sliding frictional contact between the metal of the first material and the polymeric insulator of the second material;
wherein the first object includes at least one metallic surface providing an electron target for generation of X-ray radiation; and
wherein the first object comprises a rotor.

Abstract
A high energy radiation generator utilizes sliding friction in a low pressure environment to generate high energy radiation, for example x-rays. The sliding friction may be generated by sweeping one material against a second material, for example rotating a surface of a rotor against a membrane, in the presence of an electron target, which may be one of the first material or the second material, or a different material.
