Addition of an inaudible high-frequency signal to the audio signal. It increases the signal quality of audio recordings by achieving maximum long-wavelength output and linearity.
Acceleration of electrons in the tube or system using the voltage.
Electrode in different tubes which accelerates the velocity of the electrons by emitting high positive voltage. Also known as accelerating anode.
The energy potential applied in the electron-beam tube/system to increase the energy of the electrons and accelerate their speed.
Devices used to accelerate movement of different particles, such as Van de Graaf accelerator, linear particle accelerators, cyclotrons, betatrons...
A device that measures vibration, or acceleration of various structures.
The largest angle at which the guided ray of light can be accepted by the fiber optic cable.
A dopant atom or trace impurity element that alters electrical or optical properties of the substance. It forms positive hole in semiconductors.
A thermionic cathode that consists of a tungsten filament alloyed with thorium. During heating in the absence of an electric field, thorium comes to the surface, resulting in increased thermionic emission.
