<p>A portable x-ray source that produces a sufficient x-ray flux (x) to produce high quality x-ray images on x-ray films. The source includes a vacuum chamber (20) filled with a heavy atomic weight gas at low pressure and an x-ray emitter (30). The chamber (20) is in a magnetic field and an oscillating electric field and generates an Electron Cyclotron Resonance (ECR) Plasma having a ring of energetic electrons inside the chamber (20). The electrons (64) bombard the x-ray emitter (30) which in turn produces x-ray. A pair of magnetic members (61, 62) generate an axisymmetric magnetic mirror trap inside the chamber (20). The chamber (20) may be nested within a microwave resonant cavity (10) and between the magnets (61, 62) or the chamber (20) and the microwave cavity (10) may be a single composite structure.</p> |
