Abstract
Abstract An X-ray source comprises a thin film X-ray target (22) for generating X-rays in response to the application of electron beams, and a capillary tubular element (20) for allowing the X-rays to pass. The capillary tubular element (20) has such a diameter that the beams of the X-rays impinging on the inner surfaces of the capillary tubular element (20) are totally reflected. Additionally, a thin film (24) is provided for absorbing the electron beams, but allowing the X-rays to penetrate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
70 words
An X-ray source comprising: X-ray target means for generating X-rays in response to the application of electron beams; characterized by: capillary tubular means (20) for allowing the X-rays to pass, said capillary tubular means having such a diameter that beams of the X-rays impinging on the inner surfaces of the capillary tubular means (20) are totally reflected and said capillary tubular means being faced to said X-ray target means (22).
Claim 2
Dependent Claim
70 words
An X-ray source comprising: X-ray target means for generating X-rays in response to the application of electron beams; characterized by: capillary tubular means (20) for allowing the X-rays to pass, said capillary tubular means having such a diameter that beams of the X-rays impinging on the inner surfaces of the capillary tubular means (20) are totally reflected and said capillary tubular means being faced to said X-ray target means (22).
