Abstract : In noble gases, the elevation of the electron temperature by Joule heating has been clearly demonstrated, but it has also been well established that this nonequilibrium is associated with an ionization instability. The latter leads to electron density nonuniformities and results in a change of the bulk plasma properties. MHD generators driven by molecular or combustion gases and operating at high Hall coefficients are not, a priori, immune from similar instabilities occurring either locally (over the insulators) or in the bulk of the plasma. The purpose of the present study was to determine the bulk properties of the plasma at high Hall coefficients in various molecular gases. The facility used was a disk generator driven by a shock tube. (Author)
