ABSTRACT:
An improvement of a precision manipulator for use in UHV systems with sample transfer capability in which a spring loaded thermocouple 47 and a heater electrode (51, 52) are both in direct contact with the transferred sample 35. The thermocouple and heater electrode assembly are mounted concentric with a sample receiving block 33 on the end of an offset manipulator 20. Hence, when a sample is transferred from an introduction chamber 12 into the UHV chamber 11, it contacts the spring loaded thermocouple 47 and then seats a heater electrode 52. Cooling by a copper plate 41 and a strap 22 combined with the resistance heating capability allow sample temperatures over the range of 150.degree.-1750.degree. K. while positioned in front of any diagnostic instrument in the UHV system and while taking data with these instruments.
