Abstract
The invention relates to a device for sterilization of the interior surface of packaging containers with electron beam, comprising an emitter provided with an electron exit window. The emitter is adapted to emit charge carriers, such as electrons, through the electron exit window, said electrons forming an electron cloud. The device comprises at least one outlet adapted to provide a flow of sterile gaseous medium adapted to maintain a local aseptic zone around at least an emitter portion including the electron exit window, thus preventing any flow of medium from outside the local aseptic zone from coming into the local aseptic zone. The invention also relates to a method.
