Abstract: A novel metallized film capacitor is contemplated. The capacitor includes a first film and a second film. Each of the first film and second film have a metallized layer added. Each of the metallized layers includes alternating metallized sections and margin sections. The outermost sections on one film are metallized sections, while the outermost sections on the other film are margin sections. This pattern and proper sizing of the sections creates overlap regions where a metallized section from one film overlaps a metallized section from the other film. These overlap regions create sub-capacitors that give the capacitor low inductance while allowing for high current and high voltage.

Abstract: A loaded blumlein structure is described. At one end, the blumlein can be used to generate an electromagnetic pulse. At the other end, the top and bottom conductive connected by a resistive (or more generally a lossy) connection. This allows for subsequent pulses after the initial pulse to be dampened, maintaining the amplitude of the primary pulse, while reducing the stress on the system from the later ringing of the pulse. A number of geometries are described. In other examples, a pulse dampening section connected between the top and bottom conductive strips to provide the dampening effect.

Abstract: A dual polarity transmission line structure that can provide high-voltage pulses of very short duration, such as can be incorporated in a compact accelerator of charged particles as well as other applications, is presented. The exemplary structure has a transmission line, formed a pair of conducting strip with dielectric between them, and a pair of switches. Each of the switches is connected between one of the conducting strips and a charging section, so that when the switches are off, the capacitor plates that are respectively connected to a first and a second of the switches are charged to voltage levels above and below the level at which the first and second conductive strips are set. A pulse is then generated by turning on the switches. Multiple such structures can be stacked to provide a pulse generating system.

Abstract: Improvements for optically activated electric switches are considered. Techniques are presented for reducing the peaking of the electric field at edge of the contacts. For the body of the opto-switch, methods are described to increase the number of traps. Improvements in illumination are also discussed.
