| NIKA2, the second generation Neel-IRAM-KID-Array, is a dual band camera operating simultaneously at 150 and 260 GHz. The instrument is based on large arrays of superconducting Kinetic Inductance Detectors (KID) operated at temperatures of 100mK. NIKA2 is built by an international consortium, led by the Institute Neel (Grenoble France). Successful installation took place in early October 2015. NIKA2's field of view has a 6.5arcmin diameter, with angular resolutions of 12 and 18 arcsec at 1 and 2 mm wavelengths respectively. NIKA2 is designed as a facility instrument which will remain at its present position for at least a decade. The instrument will allow to measure linear polarizations at 1.15 mm. |

Comments: A new 2mm array with 616 pixels was installed mid September 2016. The previously installed array had 1020 pixels. Further changes in September 2016 are a new dichroic frequency splitter, new lenses and a new cryostat window. In addition, several of the 20 readout electronics boards have been replaced with the last version. NIKA2 now has a homogeneous set of boards, plus several spare boards. Commissioning will start on October, 4th and will continue into the winter semester, when NIKA2 shall be opened to the community. |

NIKA2, the second generation New-IRAM-KID-Array, is a dual band camera operating simultaneously at 150 and 260 GHz. The instrument is based on large arrays of superconducting Kinetic Inductance Detectors (KID) operated at temperatures of 100mK. NIKA2 is built by an international consortium, led by the Institute Neel (Grenoble France). Successful installation took place in early October 2015. NIKA2 is designed as a facility instrument which will remain at its present position for at least a decade. The instrument will allow to also measure linear polarizations at 1.15 mm.
