The electrical conductivity of xenon plasma produced by shock waves was measured by means of a conductivity probe, similar to that described by Lin. Resler and Kantrowitz. Measurements were made for initial xenon pressures P_1 of 1-10 Torr. The shock Mach numbers M_s ranged from 8.4 to 24.5. The maximum electrical conductivity agreed with theoretical values within a factor of two. For low shock Mach numbers, the decrease in electrical conductivity and the decrease in continuum emission intensity were much faster than the theoretical decreases based on continuum radiation loss. These results indicate that line radiation losses cannot be disregarded for low shock Mach numbers. With increasing the shock Mach numbers, it was shown that e.g. at P_1=2 Torr and M_s≳20, two observed decreases could be almost explained by continuum radiation loss alone.
