Abstract
A cold finger attached to the second refrigeration stage of a DE-201 D isplex closed-cycle helium refrigerator has been equipped with a minia ture DC motor. The device allows reorientation of the crystal at low t emperature, without remounting or warming to ambient temperature. The axis around which the crystal is rotated is inclined by 45 degrees to the cryostat axis, which gives a 90 degrees change in orientation of t he crystal upon 180 degrees rotation.
