    • The plasma switching stage of a radar receiver protector is simplified and improved by the utilization of a halogen gas filled quartz container and a "keepalive" electron source. The container is configured as a capillary stem filled with low pressure chlorine gas and provides the active switching element in the signal waveguide portion of the receiver protector. An enclosed r.f. energy source in combination with the capillary stem creates a copious and steady free electron supply. The r.f. exciting field used to activate the "keepalive" plasma is enhanced by a coaxial re-entrant cavity located on the top wall of the receiver protector waveguide.
    • 雷达接收器保护器的等离子切换级通过使用充满卤素气体的石英容器和“保持性”电子源得到简化和改进。 容器被配置为填充有低压氯气的毛细管杆,并且在接收器保护器的信号波导部分中提供有源开关元件。 封闭的r.f. 能量源与毛细管杆结合产生大量和稳定的自由电子供应。 r.f. 通过位于接收器保护器波导的顶壁上的同轴凹入腔增强用于激活“保持性”等离子体的激励场。
