Status of the Large-Sized Telescope of the Cherenkov Telescope Array.

Abstract The Large-Sized Telescopes (LSTs) of the Cherenkov Telescope Array (CTA) are designed for gamma-ray studies focusing on low energy threshold, high flux sensitivity and rapid telescope repositioning. LST has a tessellated parabolic mirror 23 m diameter weight about 100 tons, with capability pointing to any position in sky 20 seconds or less catch transients. A 2 ton 3x3 camera, placed focus mirror, is equipped 1855 QE PMTs corresponding FoV 4.5 degrees. LSTs will dominate CTA performance between GeV approximately 200 GeV. first (LST-1) was inaugurated La Palma (Spain) October 2018 since then it commissioning phase. current status LST-1 discussed. behavior well understood reached design level terms sensitivity, angular resolutions. Still some work needed achieve duty cycle goal. We briefly present here physics results. Finally outlooks project presented.
