Cross-Field Current-Driven Ion Acoustic Instability,
Abstract
The report discusses the instability which occurs when electrons and ions have a relative streaming velocity, along x, V sub D > c sub s = square root of ((T sub e)/m), across a weak magnetic field, B sub Z. If (k sub x) (r sub c) mach > 1 and omega much < (omega sub ce), the spatial growth rate is enhanced by a factor K sub x/K sub z over the value at B sub z = 0. Measurements of growth rate (Im k/Re k) have been carried out in two different plasma configurations as a function of both B sub z and omega. The results are consistent with the linear dispersion relation for this instability. (Author)
