A hinge goniometer head

A stable diffractometer goniometer head for mounting crystals enclosed in high-pressure cells, cryostats furnaces, or other heavy crystal-environment attachments, has been designed. Its construction is based on a hinge, thus it is called a hinge goniometer head, and allows adjustments in three directions. Under a load of 9.8 N perpendicular to the φ axis, the goniometer head yields less than 5 µm.
