Abstract

We report here the behavior of the atmospheric pressure plasma jet when passing through a dc electric field between two parallel plates. The deflection of the plasma plume was observed by using an intensified charge-coupled device camera. The external field affects both the length and the width of the plasma plume. The plasma jet first deflects toward the positive plate, then turns to the opposite direction. The result indicates that the plasma plume is induced by high-energy electron beam from the temporal cathode.
