摘要： A solid rocket motor for accelerating a payload comprises a motor casing and a solid propellant matrix, utilizing a high burn-rate fuel. The use of a high burn rate fuel allows the rocket motor to operate in an end-burning fashion without the use of a constricting aperture to increase the back-pressure upon the burn-front of the fuel matrix. The exhaust gas produced from combustion of the propellant matrix exits directly to the ambient environment through a simple aperture without the use of an expansion nozzle. By eliminating the mass of the nozzle and allowing the use of lighter, less structurally robust motor casings, the needed acceleration of the vehicle can be achieved while using less propellant and a lighter launch vehicle.

摘要： A method for providing chemical energy and energetic compositions of matter consisting of thin layers of substances which will exothermically react with one another. The layers of reactive substances are separated by thin layers of a buffer material which prevents the reactions from taking place until the desired time. The reactions are triggered by an external agent, such as mechanical stress or an electric spark. The compositions are known as metastable interstitial composites (MICs). This class of compositions includes materials which have not previously been capable of use as energetic materials. The speed and products of the reactions can be varied to suit the application.

摘要： A field emission electron gun (10) is disclosed which has an extraction electrode, composed of one or more sharply pointed electrode tips (17) in close proximity to a field emission cathode tip (11), such that a relatively low voltage between the cathode tip (11) and the extraction electrode tips (17), in the range of 100 to 2000 volts, will cause field emission of electrons from the cathode tip due to the extremely high localized electric field at the cathode tip. The electrons in the beam extracted from the cathode (11) are at a relatively low kinetic energy, particularly adapting the beam for use in such applications as low energy electron microscopy and low energy electron diffraction. For such applications, the extracted beam is generally passed through a limiting aperture member (21), electrostatic lenses (24, 25), and a deflection coil (26) when scanning of the target (27) is desired.
