Description
An ejector is disposed near a vacuum vessel and connected to the vacuum vessel by a short pipeline. The ejector is disposed at the inner side of a boundary of a high magnetic field area of a thermonuclear device. An argon gas is used as a driving gas for the ejector. If an argon gas is supplied to the ejector by an argon gas supply pipe, gases in the vacuum vessel and the pipeline are exhausted by the effect of the ejector. The pipeline of the exhaustion side of the ejector is connected to a gas recovery device. The gas recovering device comprises an argon trap having a heat exchanger therein. The gas recovering device is connected to an argon gas reutilizing circuit. The gas recovering device is connected to a backing pump system. The backing pump system is a mechanical type vacuum pump such as a turbo molecular pump. (I.N.)
