NIKA2 Homepage

The New IRAM KID Array 2 (NIKA2) is a dual-band camera operating with three frequency-multiplexed kilopixels arrays of Lumped Element Kinetic Inductance Detectors (LEKID) cooled at 150mK. NIKA2 is designed to observe simultaneously the intensity at 1.15 and 2.0 mm. In addition, it allows for polarisation observations at 1.15 mm. NIKA2 is built by an international consortium, led by the Institute Neel (Grenoble, France).

Commissioning runs

Phase I (October 2015 - April 2017)

  • 1st run of NIKA2 (test): 29-October-2015 till 10-November-2015. Installation, cool down at the 30m, testing/debugging/developing. [= Run 13 of a NIKA instrument]

  • 2nd run of NIKA2 (test): 24-November-2015 till 02-December-2015. Continue tests started during run 1, in particular Beam maps and NEFD with the 13 NIKEL boards assembled the last days of run 1. [= Run 14 of a NIKA instrument]

  • 3rd run of NIKA2 (test): 12-January-2016 till 01-February-2016. Implementation of new NIKEL boards; the 20 data lines of NIKA2 are foreseen to be plugged simultaneously. With the 3 arrays fully read, continue and redo tests started with runs 1 & 2, in particular Beam maps and NEFD. [= Run 15 of a NIKA instrument]

  • 4th run of NIKA2 (test): 1-March-2016 till 15-March-2016. Continue tests started with previous runs, in particular investigate deeper beam patterns (XY focus, beam maps), synchronization, array 1 & 3 performances vs electronic boards, NEFD, mapping strategies. [= Run 16 of a NIKA instrument]

  • Dark run: 4-May-2016. Test sensitivity of NIKA2 to external electromagnetic perturbations, with the entrance window of the cryostat closed. [= Run 17 of a NIKA instrument]

  • 5th run of NIKA2 (test): 16-September-2016 till 11-October-2016. Upgrade NIKA2 with new dichroic, new corrugated lenses and window, new 2mm array, new NIKEL boards (get the 20 lines with homogeneous electronics, v3); redo better the tests started with previous runs (mostly beam maps in best weather conditions, but also various types of scan to investigate deeper beams and noise, synchronization, NEFD, skydips, mapping strategies, possibly polarization. [= Run 18 of a NIKA instrument]

  • 6th run of NIKA2 (test): 25-October-2016 till 1-November-2016. Continue NIKA2 commissioning. [= Run 19 of a NIKA instrument]

Reverse array 1 lens to smooth version + adjust fixation of cold mirrors block (M7-M8) to get better radio alignment of the internal optics (degraded during run 5 intervention), short test on sky to see effect of the intervention. [= Run 21 of a NIKA instrument]

  • 9th run of NIKA2 (test): 21-February-2017 to 28-February-2017. Resume NIKA2 commissioning after run 8 intervention. [= Run 22 of a NIKA instrument]

  • 10th run of NIKA2 (test): 18-April-2017 to 25-April-2017. End of commissioning phase 1, science verification. [= Run 23 of a NIKA instrument]

Phase II (June, November 2017; March, June 2018)

  • 11th run of NIKA2 (test): 8-June-2017 to 13-June-2017. Start commissioning phase 2: polarization. [= Run 24 of a NIKA instrument]
