Abstract
High energy switching device utilizing a gas discharge tube with input and output electrodes connected electrically in series with a source and a load. A control element is connected to the input electrode, and a trigger signal is applied to the control element to initiate firing of the tube to pass energy from the source to the load. An electrostatic shield is disposed about the output electrode to prevent the tube from self firing in the absence of a trigger signal when the potential between the electrodes is below a predetermined level.
Claims19
In a high energy switching device for delivering energy from a source to a load:
- a gas discharge tube having first and second electroder connected electrically in series with the source and the load, a control element connected to the first electrode, means for applying a trigger signal to the control element to initiate firing of the tube to pass energy from the source to the load, and means comprising an electrostatic shield disposed about the second electrode for preventing the tube from firing in the absence of a trigger signal when the potential between the electrodes is below a predetermined level.
In a device for delivering a high energy pulse to a load connected to a pair of output terminals:
- a gas discharge tube having an elongated envelope with axially spaced input and output electrodes disposed toward the ends of the envelope, means connecting the output electrode to a first one of the output terminals, a trigger element connected to the input electrode and disposed toward the same end of the envelope as said electrode, an electrostatic shield connected to the second output terminal and disposed coaxially of the output electrode, an energy storage device, means for delivering energy to the storage device, a transformer having primary and secondary windings, means connecting the energy storage device and the secondary winding of the transformer electrically in series with the input electrode and the second output terminal, and means for delivering a trigger pulse to the primary winding of the transformer to initiate firing of the tube to deliver the energy from the storage device to the load connected to the output terminals.
