An accurate determination of plasma densities in a Q-machine can be given by observations of electron plasma wave pulses. A universal chart to evaluate the plasma density from the propagation speed of wave pulses is provided. It is shown that the radial density distribution should be taken into account in this diagnostic method. Comparison between this method and Langmuir probe methods is presented.
