Ion transport from a laser-induced metal plasma in a vapor to a cathode surface has been investigated experimentally using conventional parallel plate electrodes and a new conceptual electrode system, which consists of an anode and two cathodes, designated as"M-type electrodes". Rapid ion transport is possible using the M-type electrodes compared with the parallel plate electrodes and there are two modes of ion transport. One is a mode similar to that seen for parallel plate electrodes, in which the bulk plasma upstreams with a velocity of 1, 160m/s during the ion extraction. The other is a special mode for the M-type electrodes, in which the plasma upstream stops at its origin and ions are transported to the parallel cathodes from both sides of the plasma.
