Description
Kinetic Inductance Detectors (KID) are based on
superconducting resonators. These last are classical devices used
since the 1960s. It was however only about ten years ago that high
performances micro-resonators, realised using thin films technologies,
was practically demonstrated. In the easiest configuration, the
detector consists merely in a single, but properly patterned, film.
Superconductivity ensures both the ultra-low losses needed to achieve
high quality factors and the sensitivity to incoming radiation thanks
to the kinetic inductance effect. Starting from the basic detection
principles, I will summarize the recent achievements in this exciting
field. These include for example millimetre and sub-millimetre
detectors for Astronomy, visible-NIR photon-counting cameras,
high-energy photon/particles imagers. I will describe in more detail
our main projects: NIKA (New IRAM KID Arrays) and NIKA2. NIKA, the
first KID-based instrument open for proposals to the astronomical
community, is installed at the IRAM 30-m millimetre telescope at Pico
Veleta (Spain). Its successor, NIKA2, is in fabrication in Grenoble. I
will briefly present selected results from the recent observational
campaigns at the telescope and the status of NIKA2.
