The IRAM Interferometer is situated on the Plateau de Bure, at an altitude of 2550 m in the French Alps 90 km south of Grenoble. It consists of six 15-m antennas movable on tracks arranged in a T-shape giving baselines up to 760 m. The interferometer was opened in 1990 with three dishes and expanded to six in 1996.
