Superconducting detectors for low-background far infrared space astronomy — •Philip Mauskopf — School of Physics and Astronomy, Cardiff University, Queen’s Buildings, Cardiff CF 24 3AA, UK
The next generation of far infrared astronomy satellites will have cooled telescopes to reduce the thermal background to very low levels. In order to take advantage of the low background, arrays of sensitive detectors will be needed, with NEPs of 10−19 W/√Hz or less - more than an order of magnitude better than can be achieved using conventional photoconductive detectors. We will review the technical requirements for such arrays and report on the development of transition edge superconducting detectors and kinetic inductance detectors suitable for use with an imaging spectrometer instrument in the 40-200 micron region.
