Abstract
Official abstract text for this publication.
An x-ray tube cathode with magnetic electron beam steering. In one example embodiment, an x-ray tube cathode includes a cathode head and an electron emitter. The cathode head includes electrically conductive and non-magnetic material integrated with magnetic material. The cathode head defines an emitter slot in a portion of electrically conductive and non-magnetic material positioned between two portions of magnetic material. The electron emitter is positioned within the emitter slot. The electron emitter is configured to emit a beam of electrons. The beam of electrons is configured to be both focused by the electrically conductive and non-magnetic material and steered during beam formation by the magnetic material.
First claim
Opening claim text (preview).
What is claimed is: 1. An x-ray tube cathode comprising: an evacuated enclosure; a magnetic yoke extending between a first portion inside and open to the interior of the evacuated enclosure, and a second portion outside of the evacuated enclosure; a cathode head comprising electrically conductive and non-magnetic material integrated with a first magnetic material portion and a second magnetic material portion, the cathode head defining an emitter slot in a portion of the elect…
