NIKA
The New IRAM KIDs Array (NIKA) is a Kinetic Inductance Detectors camera for bolometric observations at the IRAM 30m telescope. NIKA has been built by the Institut Néel (IN) and LPSC 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.

Overview
NIKA 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 following table.

- Number of KIDs = number of KIDs which resonance is probed with a tone generated by the electronics (in parenthesis = conservative number of KIDs for which no problem has been found in the data). Physically there's 224 KIDs on the 1mm array and 132 KIDs on the 2mm array.
- NEFD = Noise equivalent flux density outside of the atmosphere = sensitivity.
- HPBW = Half power beam width = angular resolution.
- FoV = effective Field-of-View calculated from area covered by all pixels.
NIKA is a prototype used to test the technologies to be used in the bigger 6.5' FOV NIKA2 instrument currently in development phase (private Wiki here).
