- W29532410 abstract "Analytical and experimental investigation of electrodeless plasma accelerators as space propulsion devices was directed toward the determination of the nature of the field-plasma interaction and the over-all performance characteristics of electrodeless accelerators. An increasing phase velocity transmission line for the study of induction and synchronous modes of acceleration was designed and constructed. Measurements were made of the conductivity, density, and velocity of the plasma produced by a button source to be used with the transmission line. Diagnostic equipment was constructed for measuring plasma conductivity, density, temperature, and velocity. The button- type sources studied proved suitable for injecting into a transmission line and capable of producing a copper plasma with densities up to 10/sup 15//cc and velocities in the area of 2 x 10/sup 4/ m/sec. Conductivities were in the range of 1000 to 1500 mho/m. Studies of the interaction of this plasma with the transmission line showed preferential trapping of plasma on the leading portion of the traveling cusp, in sharp contrast to the ineffectiveness of the trailing half of the cusp in retaining and accelerating plasma. These findings support a flux trapping concept that was devised to improve the field-plasma interaction as well as containment and disengagement of themore » plasma from the traveling field at the end of the transmission line. Also, direct evidence was found for the presence of circulating Hall currents in the accelerator. Additionally, there is strong evidence for the occurrence of a large-scale instability that developed in the reflecting wave. Data displaying the time sequential development of B/sub z/ , B/sub r/, B/sub THETA /, and plasma density in the traveling field accelerator are plotted. Application of superconductivity to traveling field devices is also discussed. The system used in the preceding studies had a low overall efficiency and thrust that, however, could be improved.
