ASD Colloquium Series
|Astronomy with Superconductors: A Review of Current and Upcoming Photon Detector Technologies
Omid Noroozian (NRAO)
Technological advances in photon detectors, spectrometers, and amplifiers have enabled increasingly more powerful telescopes, and have been at the heart of new scientific discoveries. New detector technologies have enabled entirely new observational possibilities that had not been previously considered in the design of science studies. In this talk I will review, across the electromagnetic spectrum (with some focus in the Submm/Far-IR), the state-of-the-art detector technologies that involve the use of one of nature’s strangest properties, namely superconductivity. Kinetic Inductance Detectors, Transition Edge Sensors, Quantum Capacitance Detectors, Traveling-Wave Parametric Amplifiers, on-chip spectrometers, and heterodyne receivers are all exciting technologies that will play a key role in future space and ground-based facilities, such as the Origins Space Telescope (OST), SPICA, Atacama Large-Aperture Submm/mm Telescope (AtLAST), CMB-S4, and upgrades to current facilities such as ALMA. Their science impact ranges from exoplanet atmospheric studies and protoplanetary disk evolution to large-scale spectroscopic surveys of high-z galaxies.
ASD Colloquia are Tuesdays at 3:45 pm (Meet the Speaker at 3:30 pm) in Bldg 34, Room W150 unless otherwise noted.
