Abstract The relationship between the barrier discharge characteristics and ozone generation on application of an AC voltage in a triple needle‐plane configuration has been investigated for various distances among the triple needle tips ( d =0 to 7.0 mm) with a constant distance between the needle tip and the plane ( g =3.0 mm) in dry air. The characteristics of the barrier discharge and ozone generation depend on the needle tip distance. It is considered that the influence is caused by the presence of space charge and accumulated charge, as suggested by discharge images taken by a still camera and a CCD camera. The ozone generation efficiency is also estimated from the power consumption and the ozone concentration. It is found that when the distance among the triple needle tips is small, the above influence is strengthened. In this case, the ozone generation efficiency is improved. © 2010 Wiley Periodicals, Inc. Electron Comm Jpn, 93(7): 32–41, 2010; Published online in Wiley InterScience ( www.interscience.wiley.com ).
