Abstract: An improved electron tube is provided which eliminates the need for a heated electron source and affords simplified construction. The tube, a high vacuum tube, is capable of operating over an extended range of electrical potentials. The electron tube operates on the principle of electric field effect emission for the electron source, requiring neither gas, vapor nor a heated electrode in its envelope. Two active elements, an emitter and a collector, are enclosed in an evacuated chamber with outside connections to each element. The collector is a metal plate and the emitter is an oxide-metal composite which contains a very large number of metal filaments embedded in an insulating oxide matrix. The number of filaments normally exceed one million per square centimeter of exposed surface, having ends connected on the back side to a conducting plate for external connection.

Abstract: An improved laser system is provided which increases laser efficiency, reduces power consumption and affords simplified construction. The improved laser, which can include any one of several electric pulsed systems, is capable of operating over an extended energy and duty cycle range. In operation only the electrical energy that contributes to the lasing action is drained from the energy source, thus greatly increasing the efficiency of the overall system. A mechanically biasable field effect electron emitter functions as either an active part of the laser or as an adjustable current controlling device, for controlling the period of lasing action.

Abstract: An electron gun uses a field effect emitter in a vacuum tube, providing the advantages of cold cathode emission at atmospheric temperature in addition to a simplified control system. Temperature independent emission is achieved by using an oxidemetal composite emitter for releasing electrons. The anode and emitter can be shaped to produce a desirable electric field and current path for special electron tubes.
