摘要： The present invention is related to high power X-ray sources, in particular to those ones that are equipped with rotating X-ray anodes capable of delivering a much higher short time peak power than conventional rotating X-ray anodes according to the prior art. The herewith proposed design principle thereby aims at overcoming thermal limitation of peak power by allowing extremely fast rotation of the anode and by introducing a lightweight material with high thermal conductivity (2) in the region adjacent to the focal track material (4). The extremely fast rotation is enabled by providing sections of the rotary anode disk made of anisotropic high specific strength materials with high thermal stability (1, 3, 6) which will be specifically adapted to the high stresses building up when the anode is operated, as for example fiber-reinforced ceramic materials. An X-ray system equipped with a high peak power anode according to the present invention will be capable of high speed image acquisition with high resolution and high coverage. Such a high-speed rotary anode disk can advantageously be applied in X-ray tubes for material inspection or medical radiography, for X-ray imaging applications which are needed for acquiring image data of moving objects in real-time, such as e.g. in the scope of cardiac CT, or for any other X-ray imaging application that requires high-speed image data acquisition. According to a further exemplary embodiment, the invention is directed to a rotary anode disk divided into distinct anode segments (10a, 10b) with adjacent anode segments which may e.g. be limited to each other by straight radial (14a) or S-shaped slits (14b) ranging from the inner anode bulk (1) to the inner radial edge of the anode disk's outer frame section (3). Other exemplary embodiments of the present invention relate to a rotary anode disk structure design which comprises liquid metal conductors (16a) between the inner anode bulk (1) and a rotary shaft (12) needed for rotating the rotary anode disk about its rotational axis (5), said liquid metal conductors (16a) providing a liquid metal connection between the rotary anode and its rotary shaft (12), or to a rotary anode disk structure which comprises a sliding radial connection (17) and a flexible heat conductor (18) between the inner anode bulk (1) and the rotary shaft (12).

摘要： A compact apparatus can form multi X-ray beams with good controllability. Electron beams (e) emitted from electron emission elements (15) of a multi electron beam generating unit (12) receive the lens effect of a lens electrode (19). The resultant electron beams are accelerated to the final potential level by portions of a transmission-type target portion (13) of an anode electrode (20). The multi X-ray beams (x) generated by the transmission-type target portion (13) pass through an X-ray shielding plate (23) and X-ray extraction portions (24) in a vacuum chamber and are extracted from the X-ray extraction windows (27) of a wall portion (25) into the atmosphere.

摘要： A system for irradiating material used in transfusions. The material can be pre-transfused blood, blood components and marrow. The system includes a vacuum chamber with a plate cathode inside. The cathode has a large beam electrode field-electron emissive surface with a selected cross-sectional shaped area. A power supply is connected to the cathode for generating negative high-voltage pulses and causing a selected cross-sectional shaped beam of electrons to be emitted. An electron window is also disposed inside the vacuum chamber and made of thin metal foil. The electron window receives the selected cross-sectional shaped beam of electrons therethrough and onto an electron target disposed outside the vacuum chamber. The electron target receives the selected cross-sectional shaped beam of electrons thereon and generates a selected cross-sectional shaped X-ray beam. A cathode filter is disposed next to the electron target and eliminates low energy beams from the spectrum of the X-ray beam. The filtered X-ray beam exposes the material to high energy beams for irradiation.
