Power generation experiments for a linear nonequilibrium Faraday generator with small seed fractions of 10/sup -5/ approx. 10/sup -4/ have been conducted in order to show the recovery of the effective electrical conductivity and the power density due to the suppression of ionization instability and to demonstrate the possible operation of a linear MHD generator with fully ionized seed. Results of the present experiments have shown the recovery of the apparent conductivity up to 20 approx. 27 mho/m, and the ratio of the apparent conductivity to the ideal conductivity decreases from 0.8 to 0.2 as the seed fraction increases from 1x10/sup -5/ to 7x10/sup -5/. The high apparent conductivity indicates the possible operation of a linear generator with fully ionized seed, and the increase of isentropic efficiency of a closed-cycle ineri-gas MHD generator can be expected.
