Development of Ti/Au and Hf/Au thermometers for cryogenic detectors

摘要

Transition Edge Sensors (TES) based on Ti/Au and Hf/Au bilayers are presented. By varying the relative thickness of the layers, we obtained transition temperatures of between 140 - 300 raK and 33 - 105 mK, respectively. Possible applications in the field of X-ray spectroscopy and particle detection are discussed.
