Provided is an atmospheric electron particle beam nozzle, with a nozzle body having a lumen disposed therethrough; an electrode that is disposed within the lumen, optionally concentrically with the nozzle body, to define an output chamber within the lumen that encompasses the electrode. Also provided is an atmospheric electron particle beam system that provides: a nozzle, that supplies a nozzle body having a lumen disposed therethrough; an electrode disposed within the lumen, optionally concentrically with the nozzle body, to define an output chamber; an RF generator that is in communication with a transformer having a number of turns and connected to a vacuum variable capacitor, and connected electrically to the electrode; and a fluid source that supplies the nozzle with a fluid. Also herein is a method of projecting an electron beam, by projecting an electron charged fluid sheath over a distance, and projecting the electron beam within the sheath.
