Abstract
It is an object of the present invention to provide a pulling-down apparatus that can breed a crystal having good characteristics of scintillation. The apparatus retains in a container that can control an atmosphere a melting pot having a narrow hole at the bottom side thereof, an induction heating device, and a seed-holding device that holds a seed and is pulled down so that a crystal formed successively to the seed is pulled down. Concurrently, imaging devices are arranged that can pick up images of a solid-liquid interface between the crystal and a melt material, from different directions, and the seed-holding device can be travel along directions perpendicular to respective image pickup directions in a horizontal plane.
