    摘要: This is an electron emission with a semiconductor substrate having a p-type semiconductor layer whose impurity concentration falls within a concentration range for causing an avalanche breakdown in a least a portion of a surface of the semiconductor layer. A Schottky electrode is connected to the semiconductor layer. There are a means for applying a reverse bias voltage between the Schottky electrode and the p-type semiconductor layer to cause the Schotty electrode to emit electrons, and a lead electrode, formed at a proper position, for externally guiding the emitted electrons. At least a portion of the Schottky electrode is formed of a thin film of a material selected from metals of Group 1A, Group 2A, Group 3A, and lanthanoids, metal silicides of Group 1A, Group 2A, Group Group 3A, and lanthanoids, and metal borides of Group 1A, Group 2A, Group 3A, and lanthanoids, and metal carbides of Group 4A. A film thickness of the Schotty electrode is set to be not more than 100 .ANG..

    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.
