Abstract : The properties of the electron-ion plasma are determined by the random and collective behavior of the electrons, the ions, and the neutral particles. The collective as well as the random behavior of the electrons are in most cases responsible for the character of the interaction between the plasma and an applied electromagnetic field. The measurements on the transient plasmas lead to information about ways electrons are lost such as ambipolar diffusion, recombination, and attachment. Measurements of this kind have been made on transient plasma for a long time with the microwave cavity method. Some measurements and conclusions are controversial because the interpreted effects are marginal. The effects are marginal because the measurements are done at too low electron densities. The objective is to extend the measurement that can be done through the interaction with an electromagnetic field into the high electron density range and resolve some controversial questions of the microwave cavity method.
