Abstract: A diverging magnetic field is established between the cathode and control electrode of a hollow cathode plasma switch to expand the plasma at a passageway through the control electrode, thus significantly increasing the switch's current handling capability. Preferred ranges of magnetic field strength, gas pressure, spacing between the hollow cathode and control electrode, and the mesh aperture size for the control grid are described.

Abstract: In a thyratron gas discharge device, magnetic material is located coaxially with the anode to produce a magnetic field between the anode and cathode which is substantially parallel to a discharge established between them. This causes electrons emitted from the cathode to have longer path lengths than would otherwise be the case and so the ionization density within the device is increased. This improved this operating characteristics of the thyratron and results in greater utilization of the cathode.

Abstract: A structure associated with a ceramic envelope gas filled electron tube whereby a series of concentric holes are formed through grid radiator rings which thus simulates the outer neutral gas region of a typical glass envelope tube structure. In this manner, one has created a neutral non-ionized gas flow path which shunts the main discharge in such a thyratron and which is contained within the metal internal axial structure. The apertures, as formed in the grid radiator rings, thereby provide a source path for neutral molecular hydrogen from the gas reservoir located at the base of the tube to allow the gas to be directed to the anode/grid region of the tube, where electrons are pumped and the gas is collisionally ionized. The effect serves to enhance the maximum thyratron operating frequency by allowing cool neutral gas molecules to flow into the gap region through the parallel path and then into the discharge volume of the ceramic thyratron tube. Thus, the use of such structure provides an increased maximum conduction current rating and, therefore, a greater switching capability for a ceramic gas filled tube.
Abstract translation: 与陶瓷包络气体填充电子管相关联的结构，由此通过栅格散热器环形成一系列同心孔，由此模拟典型的玻璃封套管结构的外部中性气体区域。 以这种方式，已经创建了一种中性非电离气体流动路径，其在这种闸流管中分流主放电并且包含在金属内部轴向结构内。 如在栅格散热器环中形成的孔由此提供来自位于管底部的气体储存器的中性分子氢的源路径，以允许气体被引导到管的阳极/栅格区域，其中电子 被泵送并且气体被碰撞电离。 该效果用于通过允许冷中性气体分子通过平行路径流入间隙区域，然后进入陶瓷闸流管的排放体积来增强最大闸流管运行频率。 因此，这种结构的使用提供了增加的最大传导电流额定值，并因此提供了对于陶瓷气体填充管的更大的开关能力。
