    • The invention disclosed herein includes a low pressure, light initiated, glow discharge switch for high power application. The switch is comprised of an insulating envelope formed into a cylindrical shape having conductive plates at each end. Contained within the envelope is a cathode cup and an anode cup. Each of the cups has a plate at one end which defines two central apertures. The central apertures are positioned opposite one another a short distance apart and centrally axially aligned. A quartz window at the lower end of the cathode cup defines a visual opening to allow unfocused high energy electromagnetic radiation (UV light) to be shined upon the back side of the cathode plate. When UV light is presented to the back of the cathode plate, a photoemissive mechanism is initiated which causes an avalanche effect in the gas-filled chamber of the switch which leads to the discharge of current across the gap between the anode and cathode allowing the switch to close. A system includes the electronic switch is also disclosed which may be used to trigger a high energy flash lamp or excimer laser, as well as other high power applications. A system for controlling the flow of gas into the chamber defined by the envelope of the electronic switch is also disclosed.
    • 本文公开的发明包括用于高功率应用的低压,光引发的辉光放电开关。 开关由形成为圆柱形形状的绝缘外壳构成,每端具有导电板。 在封套内包含阴极杯和阳极杯。 每个杯子在一端具有限定两个中心孔的板。 中心孔彼此相对定位,距离相对较短,中心轴向对准。 阴极杯下端的石英窗界定了可视开口,以允许未聚焦的高能电磁辐射(UV光)照射在阴极板的背面。 当紫外光呈现在阴极板的背面时,启动光发射机制,其引起开关充气室中的雪崩效应,导致横跨阳极和阴极之间的间隙的电流放电,允许开关 关闭。 还公开了一种电子开关系统,其可用于触发高能量闪光灯或准分子激光器以及其他大功率应用。 还公开了一种用于控制由电子开关的封套限定的进入室的气体流量的系统。

    • A pulse generator circuit may include a diode configured to operate as an opening switch, a tank circuit in series with the diode having an admittance that is switchable from a first value to a second value that is different from the first value, and a switching system configured to cause the tank circuit to switch between the first value and the second value. The diode may saturate in less than 100 nanoseconds. A saturable core transformer may operate as a switch that controls the opening of the diode. The pulse generator may generate a plurality of pulses, each having a length of no more than 3 nanoseconds and an amplitude of at least 1 kilovolt. Electrodes may be connected to the pulse generator to deliver the plurality of pulses to biological cells.
