Abstract The Cherenkov Telescope Array (CTA) is a next-generation ground-based observatory for gamma-ray astronomy at very high energies. Large-Sized prototype (LST-1) located the CTA-North site, on Canary Island of La Palma. LSTs are designed to provide optimal performance in lowest part energy range covered by CTA, down ≃20 GeV.
