The National Science Foundation's Daniel K. Inouye Solar Telescope (DKIST), known as the Advanced Technology Solar Telescope (ATST) until 2013, is a large solar telescope managed by the National Solar Observatory, that is currently under construction.[1] With a planned completion date of 2018, it is expected to become the world's largest solar telescope. It is a collaboration of numerous research institutions.
The telescope will have a 4.0-metre (160 in) diameter primary mirror housed in a large dome,[2] located at Haleakala Observatory on the Hawaiian island of Maui. While still under construction, the telescope was officially named after a US Senator for Hawaii, Daniel K. Inouye.[3]
Design
DKIST features an off-axis, clear aperture design. This avoids a central obstruction, minimizing scattered light when observing the faint solar corona. It also eases operation of adaptive optics and later image reconstruction such as speckle imaging.[citation needed]
The site on the Haleakala volcano was selected for its clear daytime weather and favourable atmospheric seeing conditions.[citation needed] The DKIST design is intended to enable high-resolution observations of features on the Sun as small as 30 km (20 mi).[citation needed]
Construction
The contract to build the telescope was awarded in 2010, with a then-planned completion date of 2017.[4] Physical construction at the DKIST site began in January 2013 and is currently under way as of August 2015[update][5] Work on the telescope housing was completed in September 2013.[6]
