    Abstract: A laser arrangement includes electron beam apparatus comprising a plurality of electrodes, each of which having an aperture therethrough. The apertures are aligned along the longitudinal axis of an envelope which surrounds them and contains gas. The electrodes are electrically connected such that, of an adjacent pair, one is at a lower potential than the other. An electron beam is produced between the first electrode and an adjacent electrode, and is accelerated along the axis through the apertures, the electron current increasing in magnitude. The electron beam produced is used to provide pumping powder to the gas contained within the envelope such that it acts as a laser amplifying medium.

    Abstract: An ion plasma electron gun for the generation of electron beams which exhibits electron beam dose uniformity and which is capable of varying the dose received by a material to be irradiated. Positive ions generated by a wire in a plasma discharge chamber are accelerated through an extraction grid onto a second chamber containing a high voltage cold cathode. These positive ions bombard a surface of the cathode, causing the cathode to emit secondary electrons which form an electron beam. After passing through the extraction grid in the plasma discharge chamber, the electron beam exits from the gun by way of a second grid and a foil window supported on the second grid. The gun is constructed so that the electron beam passing through the foil window has a relatively large area and uniform electron distribution which is subsantially the same as the ion distribution of the ion beam impinging upon the cathode. Means are provided for creating a pulse of secondary electrons by varying the period of time in which the secondary electrons are transmitted through the foil.

    Abstract: An integral sustainer electrode and electron beam window combination structure which is disposed across the window portion of an electron gun used in electron beam stabilized gas laser systems. The combination structure is non-reticulated and is located within a laser cavity to provide a relatively smooth nonreticulated wall which is substantially continuous with a wall of the laser cavity. In this way, supersonic flow streams of a laser gas can be introduced into the laser cavity in such manner as to minimize shock induced nonuniformities in the laser gas, and also to minimize electrode wave induced medium nonuniformities. A method of making the combination structure is also disclosed.

    Abstract: The disclosed system functions to generate ozone with improved efficiency. Oxygen gas is passed through an electric field, and while in the field is irradiated with brief bursts of high energy electrons. This produces a large number of secondary electrons in the gas and these electrons taken energy from the electric field. The secondary electrons efficiently dissociate oxygen molecules from the gas, thereby producing oxygen atoms which immediately combine with oxygen to form ozone. The electric field is pulsed on during the electron beam irradiation, and thereafter pulsed off in order to maximize energy deposition by electrons and minimize energy deposition by ions. The disclosed system may also be used to generate other substances in gas phase ionic or free-radical reactions in which a suitable gas or mixture of gases is passed through the discharge and made to react in it. For example, the system can be used to produce hydrogen peroxide or hydrazine from suitable gas mixtures of H2O + O2 and NH3 + N2, respectively.
