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 em, 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 xK sub z over the value at B sub z 0. Measurements of growth rate Im kRe 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
