Scientific Description
The IRAM 30-meter telescope is used for astronomical research in the millimeter wave-length radiation. Such as measuring the emission of molecular gas and dust, optically invisible, forming stars and galaxies, detecting organic molecules, observing the life-cycle of stars, analyzing the chemical evolution and dynamics of nearby galaxies or seeing the formation of the first galaxies in the universe

Services
Telescope

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

Equipment
NIKA2 (New IRAM KID Array 2)

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).

Spectrometers for the heterodyne receivers

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.

HERA (HEterodyne Receiver Array)

Dual-polarization heterodyne receiver comprising two arrays of 3 x 3 pixels each. Frequency range 215 to 270 GHz. Usable bandwidth 4 GHz

EMIR (Eight MIxer Receiver)

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.
