The stability of a weakly ionized, low-density (lO/sup 10/-10/sup 12/) plasma in a uniform magnetic field is considered. The plasma is in a finite conducting chamber, and there is diffusion across the field lines and streaming to the conducting end walls. Instability appears above a critical field or below a critical background pressure. The driving force is the charge separation produced by the unequal streaming of ions and electrons to the et.d walls. The unstable mode is ielical in space and rotates about the axis of symmetry. expressions are obtained for the critical field value and for the rotational velocity. (auth)
