James Clerk Maxwell Telescope (JCMT)

James Clerk Maxwell Telescope

The James Clerk Maxwell Telescope (JCMT) is the world's largest radio telescope designed specifically to work at submillimeter wavelengths; it covers wavelengths between 0.3 and 2 millimeters. The 15-meter primary dish is made of 276 aluminum panels, each of which is adjustable to keep the surface accurately configured. The JCMT is located near the summit of Mauna Kea, Hawaii, and is operated on behalf of the three partner countries (United Kingdom, Canada, and the Netherlands) by the Joint Astronomy Centre (JAC) in Hilo, Hawaii, which also operates the United Kingdom Infrared Telescope.
