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.
