Abstract
Chinese solar community has proposed a next generation ground-based solar telescope, The Chinese Giant Solar Telescope (CGST). CGST is an infrared and optical telescope whose basic objective is to resolve fundamental magnetic structure of Sun at the level of similar to 20 km in the wavelength of 1 micron. The preliminary design of CGST includes an 8-meter aperture, with light-gathering power equivalent to a 5-meter aperture. The details are given in this talk.
