A REMARK TO BEHAVIOUR OF GLOW DISCHARGES AT VOLTAGE CHANGES IN RANGE OF NANOSECONDS

A previous experimental investigation showed that the short time behaviour of glow discharges at fast changes of Cathode potential is determined by a damped plasma oscillation in the negative glow. A simple oscillation model brought satisfactory agreement between the measured quantities and those determined by this model. Only the plasma densities were 10 times smaller than the experimental values obtained by other methods. In this work it is shown that taking into account the cathode dark space in a manner analogue to the treatment of the sheath capacities in the theory of the plasma resonance probe gives correct values of densities, too. © 1969 Springer-Verlag.
