Abstract: NIKA2 is the successor to the New IRAM KID Array (NIKA), which saw first light in 2008 and improvements throughout its lifetime. NIKA2 is a continuum camera consisting of Kinetic Inductance Detectors (KIDs) which detect incident photons via a change in the (kinetic) inductance of the detectors. This method of detection is well suited to frequency multiplexing and allows for many detectors to be read out. NIKA2 has 1000 detectors at 150 GHz and 4000 detectors at 260 GHz with an instantaneous field of view of 6.5 arcminutes. NIKA2 observes with both bands simultaneously, and at 260 GHz the NIKA2 arrays are dual polarization sensitive. NIKA2 has recently been installed on the IRAM 30-m telescope at the Pico Veleta in Spain and is intended for observations of clusters of galaxies via the Sunyaev-Zeldovich (SZ) effect, deep surveys of the high redshift universe, measuring the SED of nearby galaxies, and mapping dusty molecular clouds and their magnetic fields, providing insights into stellar formation and the stellar IMF.
