摘要

Following the great success of the current generation Imaging Atmospheric Cherenkov Telescopes, the preparation of the next generation VHE gamma ray observatory Cherenkov Telescope Array (CTA) is under way. It is designed to enhance the sensitivity to gamma ray sources, to enlarge the energy band and to improve the quality of data, i.e. angular and energy resolutions, and the gamma-hadron separation (low background and systematics). A few Large Size Telescopes (LSTs) of 23m diameter will be arranged at the centre of the array to lower the threshold energy and to improve the sensitivity of CTA below 200-300 GeV. The low threshold energy provided by the LSTs will be critical for CTA studies of pulsars, and high-redshift AGNs and GRBs. The status of the design study and prototyping of elements on CTA-LST will be presented.
