Abstract
A new configuration of coaxial plasma accelerator with self‐energized magnetic compressor coil attached is described. It is shown that the circuit may be treated theoretically by analyzing an equivalent circuit mesh. The results obtained from the theoretical analysis are shown to compare favorably with the results measured experimentally. Using this accelerator configuration, glass beads of 125‐μ diameter were accelerated to velocities as high as 11 km/sec, while 700‐μ‐diam glass beads were accelerated to velocities as high as 5 km/sec. The velocities are within the hypervelocity regime of meteroids.
