GROWING OF CRYSTALS USING ELECTRON BEAM HEATING AND ANNEALIZE

摘要

A method and apparatus for growing a crystal. The method comprising, positioning the crystal and providing material similar to the material of said crystal in a region of intense electron heating whereby said material and a part of said crystal is melted and fuses together, withdrawing the crystal from the region of intense electron heating so as to promote solidification and growth of the crystal, and passing said crystal through a region of less intense electron heating to anneal said crystal.
