Abstract
The dielectric strength of the alkali-halide crystals decreases steeply with temperature in the higher temperature range. This fact cannot be explained by thermal breakdown, but it points towards a new mechanism which has been investigated in rocksalt and mixed crystals of NaCl and AgCl. The facts observed can be explained by the assumption that the intensity of the electron avalanches is decisively influenced by trapping of secondary electrons in the lattice, and their release by heat vibrations. New spectroscopic evidence for the trapping mechanism is presented.
