Concurrent irradiation with ions and electrons has been done in a high voltage electron microscope interfaced with an ion accelerator. The objective is to clarify the stability of cascades in Ge in terms of the elementary processes associated with the concurrent irradiation. Amorphous-like cascade contrast is observed under ion irradiation and increases in number eventually leading to saturation. The cascade contrast is produced within cascade regions through sequential overlaps of cascades and heavier ions form more stable cascade regions. The concurrent or subsequent electron irradiation recrystallizes cascade regions through shrinkage of the cascade contrast. Point defects and their diffusion induced by electrons contribute to the recrystallization of cascade regions.
