Abstract : This report gives a summary of the status of research on the M.I.T. nonequilibrium MHD generator, and a report on progress for the period November 1968 to October 1969. The limitations imposed on generator performance by bulk instabilities, wall layer instabilities, and end shorting are described, and possible solutions for these problems are given. Progress for the year includes more detailed diagnosis of the generator, repair of the inert gas heater, development of a coaxial preionizer, development of a slanted electrode wall, further experimental study of electrothermal instabilities, and calculation of current distributions due to simplified boundary conditions in unstable plasmas.
