CRYSTAL ORIENTATION-MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To quickly and accurately obtain a crystal surface orientation by unnecessitating the measurement of the reference position of a rotary angle. SOLUTION: A device is provided with a data-processing part for calculating the orientation of a specific crystal surface in a peripheral direction for a mark 17 of a specimen 1 byδ-reading valuesδ0+ andδ180+ for giving the peak output of an X-ray detector 5 when the specimen 1 that is a nearly circular plate- shaped crystal is rotated byδturn each at a normal position and a position where the front and revere sides are reversed.
