LLAMA (Large Latin American Millimetric Array) is a jointArgentinean-Brazilian project of a 12m mm/sub-mm radio telescopesimilar to the APEX antenna, to be installed at a site at 4800 maltitude near San Antonio de Los Cobres in the Salta Province inArgentine, at 150 km from ALMA. The scientific cases for single dishand VLBI observations include black holes and accretion disks, themolecular evolution of interstellar clouds, the structure of theGalaxy, the formation of galaxies, and much more. The antenna wasordered to the company Vertex Antennentechnik in June 2014, and theconstruction is progressing quickly; it will be installed at the sitein 2016. The radio telescope will be equipped with up to six receiverscovering bands similar to those of ALMA. Cryostats with room for 3cartridges, constructed by NAOJ (Tokyo,Japan), will be installed ineach of the two Nasmyth cabins. Among the first receivers we will havean ALMA band 9 provided by NOVA (Groningen, Holland) and a band 5 fromthe Chalmers University (Sweden). Other receivers are still beingdiscussed at the time of submission of this abstract.
