Abstract: A pair of electrodes are biased to produce an electrostatic discharge while placing a thin non electron absorbing gas layer near one or both of the electrodes which are used to develop the electric field. As a result, atmospheric oxygen, water vapor and other contaminants are removed from the regions surrounding the electrodes, allowing ionization to occur more easily. This is accomplished with an electrode structure including a hollow tube for receiving a gas, a plurality of apertures extending through the hollow tube for delivering the gas to the surface of the hollow tube, and the application of a biasing voltage for producing an electrostatic discharge in the presence of the gas. The tube can take the form of a longitudinally extending structure, or a hollow shell, depending upon the configuration of the electrostatic charging apparatus with which the electrode structure is used.
Abstract translation: 一对电极被偏置以产生静电放电，同时在用于形成电场的电极中的一个或两个电极附近放置薄的非电子吸收气体层。 结果，从电极周围的区域除去大气中的氧气，水蒸气和其他污染物，从而使电离更容易。 这是通过电极结构实现的，该电极结构包括用于接收气体的中空管，延伸穿过中空管的多个孔，用于将气体输送到中空管的表面，以及施加用于产生静电放电的偏置电压 气体的存在。 取决于使用电极结构的静电充电装置的结构，管可以采取纵向延伸结构或中空壳体的形式。

Abstract: A steady-state, glow discharge plasma is generated at one atmosphere of pressure within the volume between a pair of insulated metal plate electrodes spaced up to 5 cm apart and R.F. energized with an rms potential of 1 to 5 KV at 1 to 100 KHz. Space between the electrodes is occupied by air, nitrous oxide, a noble gas such as helium, neon, argon, etc. or mixtures thereof. The electrodes are charged by an impedance matching network adjusted to produce the most stable, uniform glow discharge.
