A unique concept is featured in the adaptation of a Bausch and Lomb Research Metallograph for remote metallography at Argonne National Laboratory. The metallograph is placed outside and adjacent to the metallographic preparation hot cell, and only the microscope section is shielded. This arrangement results in the decisive advantages of simplified adaptation for remote operation, and unaltered optical system, and greatly reduced shielding bulk. A mechanical transfer system shuttles the irradiated specimens between cave and metallograph. All controls and adjustments of the metallograph are available for use in remote metallography; microscope adjustments are manipulated with simple, hand-operated mechanical linkages; stage adjustments are motorized; camera and light source, outside the shield, are operated by hand in the normal manner. The shield, 1 1/4 in. of depleted U incorporated in the stage plus 4 in. of Pb surrounding both microscope and stage, provides for continuous operation with the equivalent of up to 50 c of Co activity. Lead-glass windows permit viewing; a reversible turret and door in the shield cubicle permit easy access to the microscope and stage. (auth)
