Abstract: A device for locating a position of impact of a projectile upon a planar surface of a target. The device includes a plurality of lamina-type parallel planes, fully covering the surface of the target. Each plane has at least two windings, disposed on its surface, which are arranged in zones forming a continuous conducting path. When a projectile breaks a winding, its location is rapidly sensed and reported. The pattern of wires and layers provides simple, direct compatibility of the output of the device with digital processing operations. An orthogonally situated second device locates the impact position in two dimensions and resolves possible errors in results due to the size of a projectile or a boundary hit. The device can also locate the impact of a second hit.

Abstract: A device for assessing an impact of a projectile with a target using optical radiation from the flash of the impact. The invention includes an optical radiation detector, which detects optical radiation from the impact flash using optical, electronic and optoelectronic devices. The optical radiation detector is situated on a tank firing the projectile at a target. Further included is an optical radiation augmenter, which is a pyrotechnic material, mountable on a projectile, for augmenting the flash of the projectile impact with the target. By analyzing the signatures of pyrotechnic materials using the optical radiation detector, one can easily identify which projectile impacted the target, determine a distance traveled by the projectile, and assess the projectile impact by ascertaining whether the projectile perforated the target.

Abstract: A flowing gas source of vacuum ultraviolet line radiation system capable of perating efficiently at low pressures and low power levels. The system includes a source body assembly having nozzle member with an orifice on one end for sustaining an electrical discharge; a vacuum vessel for providing an evacuated region outside the orifice; a cooling jacket over a gas tubular element; and an insulator mounted upon the tubular element by vacuum coupling separating the source body electrically from the vacuum vessel. The vacuum ultraviolet radiation is derived from an electrical discharge sustained in a gaseous/vaporous media which flows through a differentially pumped orifice. The inherent differential pumping at the nozzle orifice results in a reduced gas load to instrumentation which may be operatively connected to the output port of the vacuum vessel.

Abstract: An apparatus and method for detecting medium and high atomic weight eleme includes a sampling mechanism for removing particles of an element to be detected from the aerosol and confining the particles to a selected geometry. The aerosol may, for example, be pumped through a filter with the particles being confined on a defined area of the filter. The selected geometry is then irradiated with x-rays to cause the particles to fluoresce and produce secondary x-rays. The secondary x-rays are detected and analyzed using criteria which determine the identity and concentration of the particles in the selected geometry. The air stream of the aerosol through the filter can be measured to determine the volume of aerosol from which the particles were removed as an aid in determining concentration.
