James Clerk Maxwell Telescope [SEP] Introduction
In March 2015 the operation of the JCMT was taken over by the East Asian Observatory. Funding is provided by the National Astronomical Observatory of China, National Astronomical Observatory of Japan, Korea Astronomy and Space Science Institute, and the Academia Sinica Institute of Astronomy and Astrophysics of Taiwan. The telescope was combined with the Caltech Submillimeter Observatory next to it to form the first submillimetre astronomical interferometer. This success was important driving the construction of the later Submillimeter Array and the Atacama Large Millimeter Array (ALMA) interferometers.
