Radio telescope single-dish of 30 m diameter with a paraboloidal main reflector. Alt-azimuth fully steerable mounting in open air, steel on concrete pedestal, homologous design and thermally controlled. Surface precision 55 microns. Frequency range of operation 73 to 350 GHz and angular resolution 30 to 7.5 arcsec. Available backends for continuum, spectroscopy and VLBI observations
Dual-polarization heterodyne receiver comprising two arrays of 3 x 3 pixels each. Frequency range 215 to 270 GHz. Usable bandwidth 4 GHz
Fast Fourier Transform Spectrometer (FTS) with 32 GHz bandwidth and 200 kHz resolution or 8 GHz bandwidth and 50 kHz resolution. WILMA autocorrelator with 18 units of 1 GHz bandwidth and 2 MHz resolution. VESPA autocorrelator with a very high resolution of up to 3.3 kHz. Very Long Baseline Interferometry (VLBI) terminal.
Four-band heterodyne receiver dual-polarization covering between 73 and 350 GHz. Instantaneous observation of two bands with a usable bandwidth of 16 GHz, two polarisations.
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 mm (260 GHz, 2 x 1140 pixel arrays -one per polarisation) and 2.0 mm (150 GHz, 1 x 616 pixel array). 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).
