摘要

Low temperature plasma jets at atmospheric pressure are widely used for several applications including medicine. We demonstrate the potential formation on a dielectric surface whose area was 30 x 30 mm(2) by plasma irradiation. By using an array of capacitance type sensors with a spatial resolution of 1 mm, we observed that the surface was positively charged up by 3 s plasma irradiation. The surface potential had a ring shape profile when the dielectric surface was irradiated. It seems that the charge-up behavior depends on distribution of charged particles above the surface.
