Abstract: An x-ray source is described. During operation of the x-ray source, an electron source emits a beam of electrons. This beam of electrons is focused to a spot on a target by a magnetic focusing lens. In particular, the magnetic focusing lens includes an immersion lens in which a peak in a magnitude of an associated magnetic field occurs proximate to a plane of the target. Moreover, in response to receiving the beam of focused electrons, the target provides a transmission source of x-rays.

Abstract: This invention provides a source of x-ray flux in which x-rays are produced by e-beams impacting the inner walls of holes or channels formed in a metal anode such that most of the electrons reaching the channel impact an upper portion of said channel. A portion of the electrons from this primary impact will generate x-rays. Most of the electrons scatter but they continue to ricochet down the channel, most of them generating x-rays, until the beam is spent. A single channel source of high power efficiency and high power level x-rays may be made in this way, or the source can be of an array of such channels, to produce parallel collimated flux beams of x-rays.

Abstract: In a radiation imaging apparatus, an envelope has a first window for transmitting radiation and is filled with an insulating liquid, and a radiation tube in the envelope has, at a position facing the first window, a second window for transmitting the radiation, and a shielding member. A solid insulating member is arranged between the shielding member and the inner wall of the envelope, and an opening is formed at a position on the insulating member corresponding to the first window. The shortest distance from the shielding member to the first window or the inner wall of the envelope through the opening of the insulating member without the insulating member is made to be longer than the shortest distance from the shielding member to the first window or the inner wall of the envelope through the insulating member, thereby improving withstand voltage performance without reducing an radiation amount.
