Abstract

The electron transport in plasma clouds generated by a hollow cathode electric discharge are investigated. The voltage current characteristic curves indicate that the emitted current depends on bias voltage and discharge current. The measurements of the spatial dependence of the electronic density, plasma potential and electronic temperature are also presented. The energy loss rate of a high energy group of electrons with the radial distance is also measured. These experimental results are compared with a nonisothermal transport model which reproduces the spatial dependence of plasma properties
