The linear theory for plasma stability in a Hall-current plasma accelerator shows that fast magnetosonic waves can be excited on plasma inhomogeneities (magnetosonic drift instability). Two types of such waves: ''azimuthal'' and ''quasilongitudinal'': can appear, depending on the instability conditions. Experiments verify that high-frequency azimuthal waves (electron drift waves) are excited in a Hall-current plasma accelerator. These waves appear as nonlinear perturbations propagating in the azimuthal direction at approximately the electron drift velocity, cE/sub 0//H/sub 0/. Low-frequency azimuthal waves in a Hall-current accelerator have been studied earlier both theoretically and experimentally )A. I. Morozov et al., Zh. Tekh. Fiz. 42, 612 (1972) (Sov. Phys. Tech. Phys. 17, 482 (1972))). The quasilongitudinal waves studied in the present paper correspond more closely to the ''transit-time'' oscillations first detected experimentally by Yu. Esipchuk et al. )Zh. Tekh. Fiz. 43, 1466 (1973) (Sov. Phys. Tech. Phys. 18, 928 (1974))). (AIP)
