electron-beam parametric amplifier, electron beam parametric amplifier (s) (noun); electron-beam parametric amplifiers, electron beam parametric amplifiers (pl)
1. A device that boosts a signal by varying the energy pumped from an electrostatic field into an electron beam traveling down the length of a tube, and then manipulating the beam at either end of the tube.
2. A parametric amplifier in which energy is pumped from an electrostatic field into a beam of electrons traveling down the length of the tube, and electron couplers impress the input signal at one end of the tube and translate spiraling electron motion into electric output at the other end.
