Abstract
An x-ray source is described. This x-ray source includes an electron source with a refractory binary compound having a melting temperature greater than that of tungsten. For example, the refractory binary compound may include: hafnium carbide, zirconium carbide, tantalum carbide, lanthanum hexaboride and/or compounds that include two or more of these elements.
Claims20
An x-ray source, comprising:
- an electron source configured to emit a beam of electrons, wherein the electron source includes a refractory binary compound having a melting temperature greater than that of tungsten;
- a magnetic focusing lens configured to focus the beam of electrons to a spot, having a spot size, on a target;
- and
- the target configured to provide a transmission source of x-rays in response to receiving the beam of focused electrons.

A system, comprising an x-ray source, wherein the system includes:
- an electron source configured to emit a beam of electrons, wherein the electron source includes a refractory binary compound having a melting temperature greater than that of tungsten;
- a magnetic focusing lens configured to focus the beam of electrons to a spot, having a spot size, on a target;
- and
- the target configured to provide a transmission source of x-rays in response to receiving the beam of focused electrons.
1 more element
A method for providing a transmission source of x-rays, the method comprising:
- emitting a beam of electrons from an electron source, wherein the electron source includes a refractory binary compound having a melting temperature greater than that of tungsten;
- focusing, using a magnetic focusing lens, the beam of electrons to a spot, having a spot size, on a target;
- and
- in response to receiving the beam of focused electrons at the target, providing the transmission source of x-rays.
