A Liquid Nitrogen Cooler for a Specimen Manipulator of a LEED-AES Experiment

A specimen cooling apparatus which is possible to be manipulated for a LEED-AES experiment has been developed. Using the device, the specimen can be cooled to -185°C and cleaved at that temperature in UHV system. The specimen rotation is ±130° and the translation is up to ±10 mm horizontally and ±25 mm vertically.
