Ohmic heating and ionization measurements for an axial discharge in hydrogen
Abstract
Experimental results are presented on the heating effect and rate of ionization produced by an axial discharge (about 10 kA) in hydrogen gas at filling pressures of 25-400 mtorr. The electron temperature remains very low (about 1.5 eV) even at ohmic heating power levels as high as 200 MW/cu m. The results are compared with a theoretical model which assumes that the only energy loss mechanism is ionization of neutral particles. The importance of other loss mechanisms, including convection, conduction and radiation, is also discussed.
