Astronomy Colloquium (5.24/2021):Superconductivity and Astronomical Detection

05.24.2021 2:00 pm - 3:00 pm


Title: Superconductivity and Astronomical Detection

Speaker: Shengcai Shi(史生才)

Abstract: Superconductivity -- a quantum mechanical phenomenon on a macroscopic scale -- was discovered more than 100 years ago. With quantum-limited and background-limited sensitivity, superconducting detectors was not emerged until early 1980s. They are now playing an increasingly important role in cosmology and astrophysics, from millimeter-wave to Gama-ray. This talk will introduce four major superconducting detectors, namely SIS and HEB and TES and KID, and their applications in astronomy. The development status of superconducting detectors at PMO and future plan will also be addressed.   

Bio: Prof. Shi is the researcher in Purple Mountain Observatory, Chinese Academy of Sciences. He is also the chief scientist of "millimeter wave and submillimeter wave technology laboratory" of Purple Mountain Observatory, director of radio astronomy Key Laboratory of Chinese Academy of Sciences. He obtained master degree in 1988 from the Purple Mountain Observatory, and PhD degree in 1996 from the University of Japan University of comprehensive research. Prof. Shi is an expert in the research of superconductor detector physics, detector and system technology, and astronomical application.

Time: 14:00-15:00, 24/May, Monday

Venue: Room 508 (large seminar room), Department of Astronomy
