Ultrahigh vacuum holder-positioner for in situ studies of conductive nanostructures in a wide temperature range

A holder-positioner was developed in order to be used in high vacuum systems designed for synthesis and in situ samples investigation by optical methods in 77÷1171 K temperature range. During tests of holder- positioner the designed system demonstrated independence from other process chamber components, compactness, a large number of the sample degrees of freedom and the stability of maintaining temperatures in the range from 77 to 1171 K with a maximum sample cooling rate about 0.1 K/s.
