Abstract
An experiment simulating certain characteristics of the equatorial electrojet plasma (viz. Ve»re Vi ≳ ri) is described. High frequency (W ≳ Vi > ri) instabilities are observed when electrons stream in the E × B direction past ions with a velocity exceeding the ion acoustic speed. The observed phase velocities and frequencies agree with the results of the Farley-Buneman instability theory, modified to take account of finite kII. The measured instability spectrum for potential fluctuations goes as k-n ⊥ with n = 2-3.5.
