ABSTRACT:
An arc discharge device is formed by two electrodes which are hermetically sealed within a glass tube filled with an inert gas. One electrode is cup shaped, with an open end. The other electrode enters the open end and approaches the bottom of the cup shape. The distance are such that the arc discharge occurs between the bottom of the cup and the end of the other electrode. The side wall of the cup shields the arc.
