Overview of instruments
The Jiao Tong University Spectroscopic Telescope (JUST) is a 4.4-meter telescope designed for spectroscopy at the Saishiteng Mountain site in Lenghu, Qinghai. Its primary mirror consists of 18 hexagonal segments, each measuring 1.1 meters across opposite corners.
The design uses active optics to adjust the shape and position of the mirror segments, reducing the effects of temperature changes and gravity. Two Nasmyth platforms accommodate scientific instruments. One focus provides a 10-arcminute field of view; the other uses corrective optics to extend the field to 1.2 degrees. The tertiary mirror (M3) directs light to either focus.
JUST will use three types of instruments to explore the dark universe, follow transient phenomena and search for exoplanets:
(1) Multiple medium-resolution multi-object fiber spectrographs, used to observe the formation and evolution of cosmic web structures, as well as the nature of dark matter and dark energy behind them;
(2) An Integral Field Unit (IFU) array composed of hundreds of fibers and a spectrograph dedicated to rapid follow-up of transient sources in time-domain astronomy;
(3) A high-resolution spectrograph, designed to identify Jupiter-like and Earth-like planets, with the capability to characterize the atmospheres of hot exoplanets.
