The New IRAM KIDs Array (NIKA) is a Kinetic Inductance Detectors camera for bolometric observations at the IRAM 30m telescope. This is a dual band instrument using few hundreds of Kinetic Inductance Detectors (KID). The KID resonances variations which are dependent on the incoming power are probed by a comb of tones allowing to perform frequency domain multiplexing. Being a prototype in constant evolution the arrays characteristics (number of pixels, field of view, sensitivity, etc.) have evolved over the years from each test run to the other. The main characteristics of the latest configuration are summarized on the above table.
NIKA has been built by the Institut Néel (IN), in Grenoble, France under the lead of Alain Benoit, and with the contributions of other persons forming the NIKA collaboration. In 2013 the main contributing institutes are IN, IRAM, IPAG, LPSC, AIG Cardiff.
