Abstract: A solid-state pulse generator using a split magnetic core transformer is described. In one embodiment, the solid-state drive circuit uses MOSFETs switching a blumlein to produce a desired input pulses in a primary winding of the split magnetic core. The pulse length is determined primarily by the characteristics of the blumlein and the split core transformer. The “on” time of the solid-state devices can exceed the output pulse length, thereby reducing the chance of damaging voltage spikes. The use of a split magnetic core allows several solid-state drive circuits to be used in parallel to produce a single output pulse. In one embodiment, each solid-state drive circuit drives a separate single-turn primary winding of a split magnetic core transformer. In one embodiment, each core of the split core transformer has one primary winding.

Abstract: The present invention is related to methods in which an electric field pulse is applied to cells and tissue. Several embodiments of the present invention relate to the application of electric field pulses to cells to regulate the physiology and biophysical properties of various cell types, including terminally differentiated and rapidly dividing cells. Methods of regulating transcription of a gene in a cell, marking a cell for diagnostic or therapeutic procedures, determining cellular tolerance to electroperturbation, selectively electroperturbing a population of cells, reducing proliferation of rapidly dividing cells in a patient, and facilitating entry of a diagnostic or therapeutic agent into a cell's intracellular structures are also provided.

Abstract: Apparatus and method for the treatment of pollutants in gases which includes a plasma reactor chamber having sawtooth electrodes through which said gases flow, a generator of high voltage pulses of short width, high repetition rate and rapid rise time being coupled to said reactor with matched impedance, causing pulsed streamer discharges to be initiated at said chamber electrodes, increasing the effective plasma volume for more efficient pollutant reduction.

Abstract: A high-power switch network includes a laser fiber optically coupled to a network including light-initiated glow discharge switches in a Marx configuration. A low pressure gas source is used to replenish gas within the switches lost due to ionization. Each switch has a cylindrical insulating envelope with conductive end caps at each end. The end caps are electrically coupled, respectively, to a cup-shaped anode and a cup-shaped cathode. Apertures are formed centrally in closely spaced plates of the respective cup-shaped electrodes. Optical fiber cables extend through vacuum sealed ports of the switches so that the unfocused laser light is directed about the aperture of the cathode so as to close the switch, thus providing a high power output from the network.
