摘要
The low frequency ionization waves in helium surface barrier discharge at atmospheric pressure are reported. Increase in applied voltage increases wave frequency. Further the coherent oscillation excited at low voltage becomes turbulent at high voltage and finally disappears to form uniform discharge. The dispersion relation of such ionization waves is discussed. (C) 2010 Elsevier B.V. All rights reserved.
