Control of Membrane Thermal Transport Supporting Superconducting Detector Development

Because thermal transport determines the dynamic and static operation of bolometric detectors, control of the thermal conductance is critical for the implementation of detectors utilizing superconducting Transition Edge Sensors (TESs). For this reason, we have examined the use of partially perforate...

Description
Summary:Because thermal transport determines the dynamic and static operation of bolometric detectors, control of the thermal conductance is critical for the implementation of detectors utilizing superconducting Transition Edge Sensors (TESs). For this reason, we have examined the use of partially perforated membranes for thermal management. This technique preserves the physical integrity of the membrane, and therefore maintains the mechanical robustness of the detector. This paper describes investigations of the thermal transport in trenched membranes.
