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), 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.

NIKA How-to's
Pool Preparation (coming soon) provides information on the observing modes offered as well as examples of the scripts that you need to prepare to observe your project.
Observing Session (coming soon) provides an example of a typical session at the 30m telescope with GISMO.
Data Reduction (coming soon) provides some basic examples to reduce NIKA data.
Frequently asked questions (coming soon) provides answers to some commonly asked questions.
1st NIKA pool (February 2014)
The 1st NIKA pool pool will take place from the 18th of February to the 28th of February 2014. Observations will be carried from a dedicated pool account (I. Hermelo will provide login information).
