X-RAY TUBE AND NONDESTRUCTIVE INSPECTION EQUIPMENT

摘要

In an X-ray tube (1A) for generating X-rays by projecting electrons from an electron gun (17) to a target (9) of an anode (8) arranged in a tubular vacuum enclosure body (6) and taking out the X-rays from an X-ray exit window (18), the anode (8) is arranged on a tube axis (C1) of the vacuum enclosure body (6) and the X-ray exit window (18) is provided in a closing portion (5g) provided at the end of the vacuum enclosure body eccentrically to the tube axis (C1) of the vacuum enclosure body (6). With such an arrangement, the enlargement ratio of an enlarged perspective image obtained by irradiating a sample with X-rays obliquely is raised and unnecessary leakage of X-rays can be prevented.
