Transition Edge Sensor and Kinetic Inductance Detector Developments for Astronomy Applications — •Piet de Korte — SRON Netherlands Institute for Space Research

Cryogenic radiation detectors enable significant progress in astronomy through the development of Imaging Spectrometers for X-ray astronomy based on micro-calorimeter arrays of Transition-Edge*Sensors, and through the development of highly sensitive, < 10⁻¹⁹ W/Hz^1/2, bolometer arrays for Infrared and Sub-mm astronomy. The latter application can be realized both by transion-edge-sensors as well as by kinetic inductance detectors. Both developments take place at SRON Netherlands Institute for Space Research for instruments on future missions, like XEUS (ESA) and SPICA (JAXA/ESA).

The presentation will explain the principles of both type of instruments, and show the present state of development both with regard to the sensor development as well as with regard to the read-out electronics.
