Title: Progress on 1.8m Solar Telescope CLST
Biography: Changhui Rao
For better understanding and forecasting of the solar activity, high resolution solar observations are required. From 2011, we started to develop the Chinese Large Solar Telescope (CLST), which is a classic Gregorian configuration telescope with a 1.8-meter honeycomb sandwich fused silica lightweight primary mirror with ULE material and active cooling. Th e CLST is being integrated in our Institute. A solar adaptive optics system, which consists of a 451-element deformable mirror, a low-order wavefront sensor with 9×9 array, and a real-time controller, had been built for first light high resolution solar observations in G-band, Hα band, and TiO band. In this presentation the main system configuration and the corresponding post focal instruments are described. Furthermore, the latest progress and first light on-sky solar observational results of the CLST are also reported.
