Abstract:
    New type X ray tube is capable of generating X beam of rays with high spatial coherence, large dose, and large emission angle. Anode in extended electron beam or ion beam bomb structure, or structured electron beam or non-structured ion beam bomb is adopted in the invention to generate parallel-arranged linear array of emitter of X ray. Modes in structured electron or ion beam emitter, or structured grid, or electron or ion beam scan are adopted to realize emitter of X ray. Parallel-arranged periodic structure composed of high Z metal strips with narrow enough line width is adopted for structured anode. The disclosed X ray tube is workable under mode of continuous operation, or mode of pulse operation; and capable of outputting hard X ray or soft X ray. The invention is applicable to fundamental research in areas of biology, medical science, and material science etc. or in use for areas of disease diagnosis, industrial non-destructive inspection, online test etc.
