accelerating voltage

In physics, an accelerating voltage is an electric field used to speed up charged particles. These particles, such as electrons or protons, are generated by a source and then propelled through a vacuum. The difference in electric potential, or voltage, determines the energy the particles gain. For instance, an electron moving through a 1-volt potential difference gains 1 electron volt (eV) of energy.1

Particle accelerators use these voltages to achieve high energies, measured in kiloelectron volts (keV), megaelectron volts (MeV), gigaelectron volts (GeV), or teraelectron volts (TeV). While early accelerators used constant electric fields, modern designs often employ alternating electric fields, typically at radio or microwave frequencies, to repeatedly boost particle energy. This principle is fundamental to devices like television picture tubes and more complex scientific instruments like linear accelerators, cyclotrons, and synchrotrons.123
