High-speed video and optical spectroscopy have been used to monitor and account for the improved performance of a solid lubricating interfacial compound (SLIC) treatment of Cu armatures and Cu rails in a subsonic railgun. Videos were taken at 68k fra

A solid lubricating interfacial compound (SLIC) has been used to condition the rails and armature of the NRL decoy launcher, a low-speed (100-140 m/s) railgun. The study tested the hypothesis that a very thin film would protect the sliding electrical

Properly designed augmented railguns (ARGs) can operate at significantly lower currents and higher efficiency than conventional non-ARGs. This paper analyzes the performance of a two-turn and a three-turn ARG showing the design parameters that are ne

This paper presents an application of inverse analysis for determining both the temperature field histories and corresponding heat source distributions in hollow cylinders. The primary goal, however, is the development of an inversion infrastructure

A portable hard x-ray source has been developed for nondestructive testing, medical imaging, and flash x-ray radiography. The source is powered by a Marx generator that produces a 200 kV, 1.2 kA pulse of 60 ns full width at half maximum. The x-ray tu

In previous work, one module of a battery powered rapid charger was created which was able to charge the capacitor bank of a low velocity railgun [1] to 2 kV at 1 Hz in burst mode [2][3]. A second module has recently been added to the system which ha

The spatial resolution of an x-ray CCD detector was determined from the widths of the tungsten x-ray lines in the spectrum formed by a crystal spectrometer in the 58 to 70 keV energy range. The detector had 20 microm pixel, 1700 by 1200 pixel format,

The response of Nb-Al-Al/sub 2/O/sub 3/-Al-Nb superconductor-insulator-superconductor (SIS) tunnel junctions to pulsed 650-nm radiation was measured. The rise in the voltage developed across the junction increases linearly for the duration of the app
