帯電電荷による沿面放電開始現象に関する研究

抄録

This paper describes the results of an experiment in which the surface discharge initiation phenomenon is caused by the attached charge itself.We initiated the surface discharge by attaching an electrical charge to a film surface covered plane electrode using a needle electrode and lowering pressure. At a critical pressure, a ring-shaped discharge monentarily appears around the center of the attached charge. The relationship between the critical pressure and the tangential electric field is discussed with results indicating.
