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.

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).

NIKA How-to's

• Pool Preparation provides information on the observing modes offered for the continuum cameras as well as examples of the scripts that you need to prepare to observe your project.

• Calibrators (in prep.) provides flux measurements of primary and secondary calibrators for the IRAM 30m continuum cameras.

• Observing Session provides an example of a typical session with the continuum cameras at the 30m telescope.See also Data Reduction for NIKA pointing and focussing.

• For Experts: Alignment and pointing sesion (in prep.) provides a step-by-step procedure to implement a new pointing model with NIKA

• Data Reduction (in prep.) provides some basic examples to reduce NIKA data.

1st NIKA pool (February 2014)

The 1st NIKA pool will take place from the 18th of February to the 28th of February 2014.

Pool projects and observers

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

• 1st NIKA pool organization.

• IRAM 30m pool observers for the Winter 2013 semmester.

• Internal NIKA team page for organisation

Progress

The progress of the pool can be followed via:

• Pool data base

• TAPAS

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