Abstract

Abstract: KAGRA is a large scale cryogenic gravitational wave telescope currently under construction in Japan. The detector is located 200 m underground in the Kamioka mine and will employ cryogenic technologies to achieve high sensitivity. The mirrors of the interferometer will be in the form of multiple pendulums and the final stages will employ cryogenic sapphire suspension system operating at 20 Kelvin. In this paper we report the ongoing activities of the cryogenic payload group involved in the design and fabrication of the cryogenic payload system for the KAGRA detector
