Paper Abstract

Spark discharges in thin layers of liquid between solid electrode plates produce compression rings due to interaction of different shock waves. The waves are detected with fast microphones. Small piezoelectric ceramic indicators are used 40-350 mm distant from the discharge. For the nearer surrounding magnetostrictive microphones with acoustic delay lines of glass have been constructed. The shock wave interaction depends on the sound velocities of liquid and elec-trode plates as well as on the thickness of the plates. These influences are measured with X-ray flashes. The experimental data are interpolated to obtain the time and place of shock wave interaction. These investigations lead to a more de-tailed knowledge of shock and head wave interactions near spark discharges.
