Abstract : A tension-compression attachment stage for an electron microscope having a cryogenic heat exchanger is provided. The attachment stage has a support assembly for mounting brackets to support a pair of load screws and a load screw drive assembly and for mounting a fixed jaw. A moveable jaw is supported and moved by the pair of load screws. A cryogenic heat exchanger is soldered to the fixed jaw and slideably engages the moveable jaw through heat conducting slider blocks. The combination allows control of test specimen test within 1 deg-2 deg F.
