<p>A CROSSATRON plasma switch has a peak current capability in excess of 10 kA and a switching speed of at least 1x10<1><1>A/sec, making it compatible with the requirements of excimer and CO2 gas laser switches, and yet is small enough to be mechanically integrated with such lasers. It employs an axially corrugated cathode (20) with a body diameter on the order of 10 cm and axially extending shallow corrugations whose depths are about 1.0-1.5 times the distance between corrugations, together with a reduced diameter anode (22) (of about 2.5 cm diameter for an excimer laser and about 1.25 cm diameter for a CO2 laser), to obtain a plasma volume of about 50-100 cm<3> for rapid switching. A magnet assembly (40) around the cathode (20) uses only two stacked magnets (40a, 40b), but has an overall greater axial length and surface magnetic strength than in prior switches. The magnet design produces a high field strength near the cathode (20), but without a significant extension of the field into the anode region. <IMAGE></p> |
