Abstract : Experimental investigations into the nature of acoustic waves, produced as a result of intense localized RF breakdown in low pressure gases, are reported. Data concerning the velocity, amplitude, and attenuation of these waves as a function of RF power is presented and discussed. First results indicate that the attenuation is not a function of the electron density in the plasma following the RF discharge. Propagation velocities slower than the speed of sound, which have been reported previously in various gas mixtures, are discussed, and new evidence is introduced to aid in explaining the phenomenon.
