Current and near-term instrumentation at the James Clerk Maxwell Telescope

摘要

The James Clerk Maxwell Telescope is the largest submillimeter-wavelength single-dish telescope at 15-m in diameter. Under the new operation of the East Asian Observatory, it has remained at the forefront of wide-field high-resolution submillimeter astronomy in both the continuum and heterodyne regimes as a result of it's cutting-edge instrumentation. The current instrument suite includes the dual-wavelength SCUBA-2 10,000 pixel camera, the 16-pixel 345 GHz HARP array and the single-pixel 230 GHz receiver, RxA. These instruments and their scientific impact will be described. The Observatory is currently embarking on an ambitious instrument upgrade project that will include new filters and arrays for the SCUBA-2 instrument, and entirely new instruments at both 230 GHz and 345 GHz.
