| Research Abstract |
The purpose of this study is to reduce the size of co2 laser oscillators for the convenience in the utilization of them in the field of machining tools. An effective method for it is to increase the input power into the dischage gap without arc discharge. As the silent discharge, which is produced in the electrode configuration of " metal electrode-dielectric-discharge gap-dielectric-metal electrode", does not change into arc discharge inherently, we studied the phenomena of the electrical discharge in this electrode config-ration.
The ion motion was investigated by using quardrupole mass spectrometers, a small sampling orifice and differential pumping. The swarm parameters of electrons in the mixed gas for co2 laser were obtained by solving Boltzmann equation. Furthermore the ionization coefficient and the electron attachment coefficient were measured by the steady state Townsend method and the pulsed Townsend method.
