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
2
were between 0.02 and 0.2 dynes/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.
