66 -- CRYOGENIC MICROWAVE PROBE STATION SOL 52RANB50C104 DUE 071595 POC Procurement Technicians (303) 497-3221 The NIST/Electromagnetic Technology Division and the Electromagnetic Fields Division has a requirement for a cryogenic microwave probe station. The cryogenic probe station will comprise a system capable of measuring superconducting and non-superconducting microwave devices and circuits using standard wafer-probing techniques at cryogenic temperatures and in an easy-to-use configuration. The probe station will consist at least of the following: a vacuum sealed chamber with an internal cold stage capable of cooling a 3 inch wafer; continuous flow cooling system attached to cold stage with temperature control; XYZ manipulators for two (2) 40 GHz bandwidth probes for on wafer probing fixtured for low temperature operation, and all necessary accessories for standard wafer probe measurements at cryogenic temperatures including microwave probes and cables, optical microscope, windows, and heat shields.
