Elastic Interferometers as Phononic Filters for Thermal Isolation in Low-Noise Transition Edge Sensors

Djelal Osman, Stafford Withington, David J. Goldie +1

In order to achieve low Noise-Equivalent-Powers (NEP < 1 aW Hz${}^{-1/2}$) Transition Edge Sensors (TES) require high levels of thermal isolation between the superconducting bilayer…
