    摘要： A transmission target of a vacuum container is operable to have a ground potential and an electro-optical system is floated at a positive potential in the vacuum container. An electron beam, which is converged by means of the electro-optical system, is decelerated immediately before the electron beam is incident to the transmission target. The electron beam has energy that is several times of the final set value until the electron beam passes through the electro-optical system, and a divergence action exerted by a spatial electric charge effect is reduced. Color aberration of the electro-optical system is proportional to energy of the electron beam. Thus, if the electron beam is decelerated after the electron beam has passed through the electro-optical system, aberration is reduced in proportion to the degree of deceleration, making it possible to concurrently reduce a focus size.

    摘要： The present invention relates to an X-ray source for emitting a characteristic X-ray and a fluorescent X-ray analyzing apparatus using the X-ray source. A secondary target is arranged in superposition on a primary target. An electron beam generated by an electron gun enters the primary target, which passes and emits a continuous X-ray. The secondary target transmits and emits a characteristic X-ray excited by the continuous X-ray emitted from the primary target. The primary target and the secondary target are superposed one on the other, so that the continuous X-ray emitted from the primary target efficiently excites the secondary target thereby to efficiently generate the characteristic X-ray.

    摘要： The present invention is to clear the difficulty in determining the progress of the decomposition reaction of PCBs carried out by a conventional device for decomposing PCBs, and to provide a system for treating PCBs to render them harmless, capable of continuously determining the progress of the decomposition reaction of PCBs at real time by using a predetermined amount of a reaction solution taken out while the decomposition reaction of the PCBs is proceeding.The quantity of the polychlorobiphenyls existing in a polychlorobiphenyl-containing liquid can be determined by the system for treating polychlorobiphenyls to render them harmless according to the present invention in the following manner: a polychlorobiphenyl-containing liquid is irradiated with exciting light of from 400 nm to shorter than 450 nm, that can excite the polychlorobiphenyls, or with exciting light of from 300 nm to shorter than 400 nm, that can excite the decomposition products of the polychlorobiphenyls, and the intensity of the emitted light is measured at a wavelength between 450 nm and 600 nm, both inclusive; and the quantity of the existing polychlorobiphenyls is determined based on one of the values measured, or based on the ratio between the two values measured. The progress of the decomposition reaction of the polychlorobiphenyls can thus be determined, and the polychlorobiphenyls can be fully and sufficiently decomposed.
