ENGINEERING ASPECTS OF ELECTROMAGNETIC ENERGY ADDITION TO A GAS BY A TRAVELING MAGNETIC FIELD.
Abstract
Research on a traveling wave plasma accelerator for ultimate use as a high altitude, high velocity flow simulation device is reported. The work reported covers: the design, construction and testing of acceleration coils for field levels up to 500,000 ampere turns per meter at 100 KHz; the predicted performance of increasing phase velocity accelerators using equilibrium air at these field levels, computed numerically from the one dimensional equations of motion including friction and heat transfer; analysis of a finite accelerator having a phase velocity which increases with length; a description of model accelerator coils with velocity ratio of 2.5; and methods of eliminating losses connected with the fringing field at the ends of an accelerator coil. Earlier calculations of the performance of an accelerator with a magnetic core are also extended, and experience with extension of the operating power level of the RF plasma source is briefly discussed.
