Abstract
A plurality of electrodes (7, 10) are arranged along two rows facing each other in pairs, leaving a spark gap in between the rows of electrodes. Each row comprises a plurality of electrodes connected in parallel. The electrodes are in a gas. The problem is to trigger simultaneous arcs between each pair of electrodes. This is achieved by extending an insulated conductor (15) parallel to the rows and then in applying pulses to the insulated conductor to obtain a corona discharge around it. The resulting ions suddenly reduce the striking potential across the spark gap. A potential difference is applied across the gap by a generator (12). The potential is below the nonionized striking potential and above the ionized striking potential. The sudden drop in striking potential ensures that all pairs of electrodes strike substantially simultaneously. The apparatus can be used to excite a high repetition rate gas laser generators.
