System for transferring samples between chambers in UHV

Abstract

This system provides right angle or end-on transfer of a sample holder from one chamber to another at ultrahigh-vacuum conditions. A convenient mechanical coupling and uncoupling device and magnetically driven transfer rods allow movement of the sample-holder assembly over distances up to 150 cm. The room-temperature holder accommodates two samples. The heatable assembly includes contacts for resistive heating of the sample to temperatures above 1800 K and thermocouple reading of sample temperatures.
