Cryomechanisms and cryocomponents

Since now optimized electrical mechanisms and components for use at low temperature are scarcely available on the market. In the case of need mostly improvisation or modification of failed components is necessary. Within the frame of this contract a selection of typical components was developed and tested under respect to the special requirements are cryogenic conditions and production guidelines were worked out. In detail an electric motor, an angular encoder/decoder, electrical feedthroughs, a cold multiplexer and an electromotor using high-Tc-superconductor were manufactured. (orig./MM)
