    Abstract: A solution electrode glow discharge apparatus has a housing that contains a solid electrode. The solid electrode has a head and a tip. The tip of the solid electrode extends outwards from the housing. At least a portion of the head of the solid electrode is positioned with an electrical and thermal conducting block. An adjustable-polarity power supply is provided in communication with the solid electrode. A cooling mechanism is provided for cooling the electrical and thermal conducting block.

    Abstract: The liquid metal cathode is employed as a cathodic electron source in arc discharges. A small liquid metal pool serves as the arcing material, and when it is kept small, improved electron-toatom emission ratios are obtained, as well as gravity independence. However, when such a small pool is employed, feed to the pool must be free of feed rate perturbations. Otherwise, an instability in the level of the mercury in the pool results. The present invention obtains feed rate stability by providing a feed passage with a diameter which is everywhere larger than that of the feed channel which finally discharges to the pool. Feed flow impedance is provided by an elongated capillary feed channel.
