The basic characteristics of a micro-cell plasma in a gas mixture sustained by a high-frequency voltage source with a ring-shaped electrode are described in this article. The key to maintaining a microcell plasma is to reduce wall loss and increase plasma production. The advantage of a gas mixture of Ne/Xe is the increase of the plasma production rate in a low electric field compared to that in pure gas. As a result, a microcell plasma can be sustained by a lower applied voltage by using a gas mixture of Ne/Xe under the same power condition as compared with that in pure Xe.
