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 dynessq 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
