Abstract : An experimental study of the establishment of non-equilibrium ionization in flowing cesium-seeded argon has been continued with emphasis on rate controlled aspects. In addition to the usual ionization and recombination rates, a seed diffusion rate to the electrodes and an electrode thermal inertia have been identified as possibly important in certain applications involving short running times. From the limited amount of data obtained, it was found that an applied transverse magnetic field increased the plasma power dissipation rate with respect to conductivity, the overall electron density recombination rate, and the required plasma breakdown voltage.
