Title: Method for monitoring atmospheric pressure glow discharge plasma
Inventor: OKAZAKI SACHIKO
IPC: C23C16/54
Filed: 1992-07-16
Abstract: PURPOSE:To monitor plasma properly, quickly, and simply by sensing the num ber of current pulses. CONSTITUTION:In the case of glow discharge plasma, the number of current pulses are monotonous substantially, while it is complicated in the case of silent discharge. Therefore, silent discharge is avoided by acknowledging typical cases through grouping distinctly to enable stabilized atmospheric pressure glow discharge. A circuit to monitor the number of current pulses in such a fashion is demonstrated in the attached illustration with a discharge tube given as an equivalent circuitry, where (r) represents discharge impedance and Cd equivalent capacitance, and the current Ic is the capacitance component of a discharge current at the impressed power frequency while Ir is the real discharge current. Because the measuring current Id includes the two, it is measurable while separated from the capacitance component by passing the discharge current pulses through a high frequency filter. The pulse current in atmospheric pressure glow discharge is proportional to the discharge current value in case the number of pulses is one per half cycle but presents a number of fine discharge conditions in silent discharge to permit observing easily.
