Paper Abstract

A new method to find the ion density of a gas at any time after the discharge is described. In this method the overvoltage of a fast discharge in a gas or its lasing action can be used. That is to say, knowing the experimental values of the actual starting voltage of a pulsed gas discharge or the laser output and comparing them with the relevant theoretical values, the ion density can be found. The result of this procedure is the calculation of the ion density at a time after the discharge equal to the inverse of the high voltage pulse repetition rate. Thus, by changing this pulse repetition rate the temporal behaviour of the ion density is found. An application to the N2 gas leads to the calculation of the ambipolar diffusion coefficient, the value of which is in sufficient agreement with the one in the literature.
