INDUCTIVE METHOD OF REGISTRATION OF SHOCK-WAVE PARAMETERS IN CONDENSED MEDIA

We discuss a method of measurement of particle velocity behind a shock wave front in a condensed dielectric medium. The method is based on re cording of the electromotive force (emf) that is induced in a current- carrying coil when the shock wave deforms it. A toroidal probe coil wa s used to reduce electrical noise. A current of 500 A was supplied to the coil by means of aperiodic discharge of a capacitor. The recorded emf amplitude is proportional to the measured particle velocity and eq uals 20 V for a velocity of 1 km/sec. The influence of some phenomena accompanying shock-wave propagation along the coil on the accuracy of the particle-velocity measurements was estimated.
