Liquid-metal plasma valve has an anode a condenser, and a force-fed liquid-metal cathode. These bound the interelectrode space through which the plasma jet acts during conduction. The cathode directs the plasma jet to impinge on an inclined surface which acts as he anode. The inclined surface reflects the particles to the condenser when the anode is noncondensing, but when the functions of anode and condenser are combined, the inclined surface of the condensing anode traps the jet particles. When the anode is noncondensing, in some cases the condenser and anode are at the same potential and in other cases the condenser and cathode are at the same potential. Cathode anode and condenser are …
