Ray cathode
Web$\begingroup$ Strictly speaking, this is not a cathode ray tube. It could be called a plasma glow discharge tube or a vacuum diode. A CRT would be similar but would have the anode close to the cathode and it would have a hole in it for the accelerated electrons to pass through. The cathode rays would be the beams of electrons passing beyond the ... WebApr 15, 2024 · Cathode ray tube Structure & working method The tube consists of a metal surface called the cathode, The cathode is heated by a filament, electrons are emitted from the electron gun (E – gun), due to heat, some electrons may overcome the forces of attraction at the surface (surface potential barrier).
