RESEARCH PROGRAM ON CONVERSION OF EXPLOSIVE ENERGY
Abstract
Magnetic field compression experiments were continued, using an interim 1000 joule bank. The circuit parameters of this system were investigated to calculate the magnetic field in the load prior to its explosive compression. The signals induced in the pick-up loop during the firing were then analyzed in terms of a simple model picturing a constant total flux trapped in an area that is decreasing due to the expansion of the copper-clad explosive. The most successful compression was from an initial field of 4700 gauss to a final field of 38,500 gauss, or by a factor of 8.2. Efforts to obtain higher magnetic fields by redesigning the load coil and explosive piston and by working toward a higher initial magnetic field are continuing. Conductivity studies are being directed toward removing possible secondary effects in the conductivity measurements. These include the confinement of the detonation and consequent changes in the reaction zone due to the structure supporting the double probes and the Tprobes, the effect of the T-probe plate thickness, the difference between internal and surface conductivity measurements, and air-shock induced conductivity.
