Abstract: The origin of the oscillations in the range 1-100 liHz which have been observed during the working of a stationary plasma thruster is not well understood until now [I].Our purpose is first to clarify the nature of these oscillations and second to propose a new explanation using the concept of current instabilities proposed by Buneman [2].To reach this objective, a spectral study of the linear instabilities has been performed with a stationary quasi -neutral hybrid model ([3],[4]). Thesc computations show unam…
