An X-ray source includes a thin film X-ray target for generating and focusing X-rays in response to the application of electron beams, and a capillary tubular element for allowing the X-rays to pass. The capillary tubular element has such a diameter the beams of the X-rays impinging on the inner surfaces of the capillary tubular element are totally reflected. Additionally, a thin film is provided for adsorbing the electron beams, but allowing the X-rays to penetrate.
