NIKA

The New IRAM KID Arrays (NIKA) is a dual-band (150 and 240 GHz) Kinetic Inductance Detectors camera for continuum observations at the IRAM 30m telescope. NIKA has been built by the Institut Néel, LPSC, IPAG and IRAM Grenoble, and the University of Cardiff. NIKA comprises two focal planes: 132 pixels at 120-170 GHz and 224 pixels at 200-280 GHz. NIKA covers simultaneously in the two bands the same portion of the Sky with an instantaneous field-of-view of 2 arc-min.

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).

  • Go to the NIKA wish list.

Call for proposals

NIKA is offered for the first time to the community the winter semester 2013/14:

Open runs

3rd NIKA pool (Jan-Feb 2015)

The 3rd NIKA open pool will take place from the January 27th to February 10th.

For information about the accepted projects and the observers at the 30m please go to:

The progress of the pool can be followed via:

Both databases are synchronized and can be used to write/read the logsheet.
