Paper Abstract

Hyper Suprime-Cam (HSC) is a next generation wide field optical camera developed for F/2 prime focus of the 8.2 m Subaru telescope. The focal plane is about 600 mm in diameter where 116 CCDs (2k4k 15 micron square each) are arranged and cooled down to -100°C. The HSC CCD cryostat system design is presented by Komiyama et al. (2010). Since then, we made detail designs of the components, manufactured them and assembled the dewar. This paper presents the actual performance of the system including flatness and parallelism of the SiC cold plate, stability of its temperature, the amount of out-gassing.
