阴极射线 Cathode ray

(重定向自Electron beam)
克鲁克斯管示意图。-A-是低压电源,提供阴极-C-加热的能量。-B-是高压电源,为覆磷的阳极-P-提供电压。-M-是蒙片,其电位与阴极相同,其图像显示在屏幕上磷不发光的部位

阴极射线是在真空管中可以观察到的电子流。真空管是一个被抽成真空的、装有两个电极(一个阳极和一个阴极)的玻璃管。

阴极被加热后,其释放出来的电子会像射线一样飞往阳极。假如阳极后面的玻璃片覆有磷光物质的话,它会发光。阴极与阳极之间的金属板会在磷光玻璃板上留下影子。这说明磷光是由阴极发射出来的粒子打到磷光板上后发出的。这些粒子直线地从阴极飞到阳极,并飞过阳极一段距离。

Cathode ray 阴极射线

(重定向自Electron beam)
A beam of cathode rays bent into a circle by a magnetic field generated by a Helmholtz coil.   Cathode rays are normally invisible; in this tube enough residual gas has been left that the gas atoms glow from fluorescence when struck by the fast moving electrons.
A diagramatic Crookes tube showing the connections for the high voltage supply.  The Maltese cross has no external electrical connection.

Cathode rays (also called an electron beam or e-beam) are streams of electrons observed in vacuum tubes. If an evacuated glass tube is equipped with two electrodes and a voltage is applied, the glass opposite of the negative electrode is observed to glow, due to electrons emitted from and travelling perpendicular to the cathode (the electrode connected to the negative terminal of the voltage supply). They were first observed in 1869 by German physicist Johann Hittorf, and were named in 1876 by Eugen Goldstein Kathodenstrahlen, or cathode rays.
