katodestrålrør
Katodestrålrør, often abbreviated as KTR, is a vacuum tube technology that was widely used in electronic devices for displaying images and generating radio waves. Its fundamental principle involves the emission of a beam of electrons from a heated cathode. This electron beam is then accelerated and focused by an electron gun, which consists of several electrodes with specific voltage potentials.
The focused electron beam is directed towards a phosphorescent screen located at the front of the tube.
Beyond display devices, katodestrålrør have also been employed in oscilloscopes for visualizing electrical signals and in
