Kombinierte Licht‐ und Radiowellenemission während des Bruches von Partikeln

The relationship between the light and radio impulses that appear during the stressing layers of glass particles was investigated. Particles were stressed between two metallic plates under applied high voltage. The emission of light appears during the development of the first cracks within the particle. The radio wave impulses were caused by electrical breakdown of a fragment layer. It appears after the light impulse. The delay between light and radio impulse of about a few micro seconds represents the characteristic time of size reduction.
