|The National Large Solar Telescope (NLST) is a 2-m state-of-the-art telescope that will provide a front ranking international facility on Indian soil to carry out high spatial and spectral resolution studies of the solar atmosphere, that include the accurate measurements of magnetic fields with high sensitivity.
The telescope utilizes an innovative design with low number of reflections to achieve a high throughput and low polarization. High order adaptive optics is integrated into the design that works with a modest Frieds parameter of 7-cm to give diffraction limited performance. The telescope will be equipped with a suite of post-focus instruments including broad and narrow band imagers, a high resolution spectrograph and a polarimeter.
A comprehensive site characterization programme has identified Hanle in the Ladakh region of Jammu and Kashmir for NLST. This site has consistent good seeing, a large number of sunshine hours and very low water vapor content, that makes it ideal for infrared observations.
The main science goals of NLST include: a) Magnetic field generation and the solar cycle; b) Dynamics of the magnetized photosphere & chromosphere; c) Helioseismology; d) Prominences; and e) Activity.
This project is led by the Indian Institute of Astrophysics and has national and international partners. Its geographical location will fill the longitudinal gap between Japan and Europe.
