Abstract : An alternate description of the Plasma Opening Switch (POS) is presented. In addition, a preliminary study was conducted into the ionization of desorbed carbon particles from the cathode surface in the switch region. The formation of a locally dense plasma layer surrounding the cathode is shown to influence the electric field and the Debye screening distance. This effect influences the emission of electrons from the cathode as well as providing a mechanism for opening the switch. Keywords: Plasma opening switch, Plasma sheath model.
