The non-equilibrium response of a superconductor to pair-breaking radiation measured over a broad frequency band
P. J. de Visser, S. J. C. Yates, T. Guruswamy +7
We have measured the absorption of terahertz radiation in a BCS superconductor over a broad range of frequencies from 200 GHz to 1.1 THz, using a broadband antenna-lens system and…
Quasiparticle effective temperature in superconducting thin films illuminated at THz frequencies
Tejas Guruswamy, David J. Goldie, Stafford Withington
The response of superconducting pair-breaking detectors is dependent on the details of the quasiparticle distribution. In Kinetic Inductance Detectors (KIDs), where both pair break…
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) Transition Edge Sensors (TES) require high levels of thermal isolation between the superconducting bilayer…
Nonequilibrium superconducting thin films with sub-gap and pair-breaking photon illumination
Tejas Guruswamy, David J. Goldie, Stafford Withington
We calculate nonequilibrium quasiparticle and phonon distributions for a number of widely-used low transition temperature thin-film superconductors under constant, uniform illumina…
