    • The present invention is directed to an apparatus for producing a vacuum arc in a plasma centrifuge. The apparatus comprises a cathode (7) of a material from which the vacuum arc is formed and a trigger electrode (11). A trigger circuit (27) is coupled to the trigger electrode for storing energy and then applying a break down voltage between the cathode and the trigger electrode where the cathode breaks down and initiates the vacuum arc. A pulse forming circuit (9) is electrically coupled to the cathode for supplying a constant current pulse to the cathode to enhance the formation of a completely ionized plasma. The resistance of the pulse forming network (23) is lower than the impedance of the vacuum arc. The present invention also is directed to an anode grid holder for use in the plasma centrifuge.
    • 本发明涉及一种用于在等离子体离心机中产生真空电弧的装置。 该装置包括形成真空电弧的材料的阴极和触发电极。 触发电路耦合到触发电极,用于存储能量,然后在阴极和触发电极之间施加击穿电压,其中阴极发生故障并启动真空电弧。 脉冲形成电路电耦合到阴极,用于向阴极提供恒定电流脉冲以增强完全电离等离子体的形成。 脉冲形成网络的电阻低于真空电弧的阻抗。 本发明还涉及用于等离子体离心机中的阳极栅格保持器。
