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.
