Status of the CTA Large-Sized Telescopes — •Martin Will for the CTA collaboration — Max-Planck-Institut für Physik

The Cherenkov Telescope Array (CTA) is the next-generation observatory for ground-based gamma-ray astronomy at very high energies. CTA will consist of two arrays, one in the northern hemisphere at the Roque de Los Muchachos Observatory on La Palma (Canary Islands, Spain) and one in the southern hemisphere at the Paranal Observatory in the Atacama Desert (Chile).

The Large-Sized Telescope (LST) is one of the three types of telescope in CTA. With a reflective surface diameter of 23 meter, LSTs are optimized to detect low-energy gamma rays in the range 20 GeV to 3 TeV. LST-1 in La Palma is close to finishing its commissioning phase, while construction has begun on the next three LSTs.

In this presentation, the status of the LSTs in the North and plans for the LSTs in the South will be shown.
