- 論文の詳細を見る
An X-ray tube with a rotating anode and an electro-static lens was constructed, in which the cathode instead of the anode was earthed. Each of the Cu and Fe characteristic rays is obtained without breaking vacuum. An adjustment of position of a camera can be made with quite security, since the total area on the side of a window emitting X-rays is earthed. By this tube, photographs of metals and oxides can be taken in 10sec and 1min respectively, using Cu radiation filtered by a nickel foil, the voltage and the current being 50kV and 30mA respectively, when the electron beam is focussed in an area of 0.25mm × 0.75mm by a biasing voltage of about 600V.
