Abstract

A device for generating an x-ray point source includes a target, and an electron source for producing electrons which intersect with the target to generate an x-ray point source having a size which is confined by a dimension of the target.

Claims (7)

1. A device for generating an x-ray point source comprising:

a target; and

an electron source for producing an electron beam which is one of collimated and focused, said beam intersecting with said target to generate an x-ray point source having a size which is confined by a dimension of said target,

wherein said target comprises a membrane,

wherein said target further comprises an insulating layer and a metal cladding formed on said insulating layer, and

wherein said membrane comprises a membrane tip which is formed on an end portion of said target, said electron beam being incident to said membrane tip from a direction inside said target.

2. The device according to claim 1 , wherein a vacuum is pulled on said inside of said target.
