Abstract

A magnetooptical rapid-action shutter was used to study the formation of cathode spots on the electrodes of a short-time high-intensity electric discharge. It was found that there exist two types of cathode spots. Spots of the first type are transported with a high velocity to the cathode surface not yet reached by the discharge. Spots of the second type, on the other hand, move in the neighbourhood of the centre of evaporation. On metals which evaporate with difficulty (Ni, Cu, Al) only spots of the first type may exist. On metals which easily evaporate (Cd, Sn, Zn) spots of both types exist simultaneously. The formation of cathode spots is explained by means of the cold emission of electrons from the cathode.
