Abstract
Method and apparatus for generating X rays by laser impingement on a target in a vacuum enclosure to generate plasma, wherein the target comprises a first film made of a suitable metal and a second film made of an X-ray transmitting material and superimposed on one surface of the metal film, and with a space being formed between opposite parts of the first and second films, a laser beam is projected onto the part of the metal film which corresponds to the space, so that plasma is generated and confined in the space for a longer time than otherwise, thereby to increase the efficiency of X-ray generation.
