Abstract

An x-ray generator device includes a housing at least partially holding a specific fluid pressure, with an arm positioned to be able to strike a strike plate within the housing. The housing contains an x-ray window. The arm is magnetically actuated in at least one direction by a magnetic field generator outside of the housing. A striking portion of the lever arm and/or the strike plate may be a polymeric material with embedded metal or metal alloys.

Claims

1. An x-ray device, comprising:

a chamber at least partially evacuated of gases;

a spring leaf with at least one end within the chamber, at least a portion of the spring leaf within the chamber forming a striker, the spring leaf coupled to a fixed magnet;

a strike plate within the chamber and positioned to be struck by the striker, with a portion of the strike plate to be struck by the striker of a material that charges negative relative to material of a striking portion of the striker;

a magnet outside the chamber, the magnet coupled to a spindle of a motor; and

control circuitry to drive the motor such that rotation of the spindle causes rotation of poles of the magnet at a frequency about a resonant frequency of the spring leaf.

2. The x-ray device of claim 1, wherein at least one of the striking portion of the striker and the portion of the strike plate to be struck by the striker is insulated from ground.

3. The x-ray device of claim 1, wherein the strike plate comprises an electrically insulating material.

4. The x-ray device of claim 1, wherein the strike plate comprises a membrane.

5. The x-ray device of claim 4, wherein the membrane is part of a polymeric band.

6. The x-ray device of claim 1, wherein a pressure within the chamber is less than 50 mTorr.

7. The x-ray device of claim 1, wherein a pressure within the chamber is less than 100 mTorr.

8. The x-ray device of claim 1, further comprising a getter material within the chamber.

9. The x-ray device of claim 1, wherein the chamber includes a sealable orifice.

10. The x-ray device of claim 1, wherein the striker and the strike plate are removable from the chamber.
