ACOUSTICAL EFFECTS IN A NEON GLOW DISCHARGE.
Abstract
The pressure oscillations accompanying the moving striations in the positive column region of a neon filled discharge tube were observed using a specially constructed and calibrated condenser microphone probe. During stable discharge conditions when the moving striations could be observed optically, pressure amplitudes measured were between 0.02 and 0.2 dynes/sq cm, depending upon ambient pressure and discharge current, with a frequency which was always at the repetition rate for the striations. Frequency was observed to be a function of pressure and current. For any given condition of pressure and current, only one frequency was observed, suggesting excitation of a normal mode. A theory to explain such a normal mode excitation in the discharge is postulated. (Author)
