Perhapsatron, Early Fusion Power Device
The Perhapsatron was an early fusion power device based on the pinch concept. In a pinch device, the required magnetic field was created by the plasma itself. Since the plasma is electrically conductive, if one were to run a current through the plasma, it would create an induced magnetic field. This field, through the Lorentz force, will act to compress the conductor. In the case of a plasma, the force would collapse it into a thin filament, pinching it down. Since the current had to be very large, pinch devices made no attempt to confine the plasmas for extended periods. They would attempt to reach fusion conditions quickly and then extract power from the resulting hot products. The first example was built in the winter of 1952-53, and it quickly demonstrated a series of instabilities in the plasma that plagued the pinch concept. A series of modifications followed which attempted to correct these problems, leading to the ultimate S-4 model.
