Abstract : Expriments are reported which illustrate the propagation of acoustical waves established in a low pressure gas following breakdown by a very high power magnetron pulse. The waves, which travel at about the velocity of ordinary sound, are shown to have properties which can be attributed to both ordinary sound and a type of combined electron-ion oscillation known as pseudo sound. The gases used are xenon, helium, and nitrogen at pressures ranging from 2 to 10 mm Hg. Peak pulse power is 275 kw, pulse width 1 microsec, and frequency 3 kmc. A proposed experiment to study the nonlinear interaction of EM waves with low energy shock waves is also discussed. (Author)
