月 日現在 ２８ ６ １円 11,400,000研究成果の概要(英文)： The LST of the CTA is designed to achieve a threshold energy of 20GeV for HE gamma rays.The dish of the LST is composed of 198 hexagonal 1.5m mirrors.The mirror facets are actively aligned during operations by an AMC system.To correct a direction of the optical axis of a each mirror facet, the AMC system uses two actuators, a CMOS camera, and a reference laser.The AMC system has been developed for these three years and achieved a high performance of 2 arcsec to control optical axis direction.This specification is exceeded our original goal of 14 arcsec.Furthermore an algorithm for extended AMC system was developed to control 198 mirrors on the LST simultaneously by method of clusterised all mirrors divided into ten mirrors in each group.The mirrors with the AMC system is expected to install a first LST at La Palma in early 2017.
