Ev --> electron-volt

(Science: unit) a general unit of energy of moving particles, equal to the kinetic energy acquired by an electron losing one volt of potential, equal to 1.602 x 10-19 j.

this is the energy an electron (or other particle of charge=1 such as a proton), gains as it is accelerated through a potential difference of 1 volt. In plasma physics the electron-volt is used as a unit of temperature when the mean particle energy is 1 ev, the temperature of the plasma is roughly 11, 600 kelvin (the conversion from ev to k is via the Boltzmann constant).
