Reader [Xellers] sent in his newest instructable: DIY Electron Accelerator: A Cathode Ray Tube in a Wine Bottle. While not exactly what you might think of a cathode ray tube, the basics are in place.

The energy of cathode rays, which were generated in a gas tube worked by an induction coil, was about 50 kilo electron-volts, the wave-length of the corresponding material waves being about 0.055 A.

Carbon nanotubes, with their superb electron-emitting properties ... flat panels have overthrown the 80-year reign of the cathode-ray tube (CRT) to become the dominant television technology.

Others thought the rays were streams of particles. J.J. Thomson decided to find out for sure. Thomson was a physics professor at Cambridge University in the UK. He placed cathode tubes in electric ...

Cathodes emit electrons in sputtering systems, cathode ray tubes, and other vacuum tube systems ... Cathodes are widely used in batteries, electrolysis systems, plating, electrochemical devices, fuel ...
