Tempering chamber for preparation of atomically pure surfaces

The chamber consists of two telescopically arranged tubes. The fixed tube is provided with a piezoelectric resonator for evaporated particle display. A thermocouple is flexibly attached to the movable tube which, when the tube is slipped on a rotary manipulator with the sample, is in flexible contact with the sample surface. The movable tube is supported with an arm operated through a rotary bushing in the wall of the vacuum chamber recipient. The axes of analysis systems (coaxial Auger analyzer, LEED optics) and the tempering chamber axis lie in the plane of the sample to be studied. (H.S.)
