HyperSuprime: mechanics

摘要

A next generation wide-field camera, HyperSuprime, proposed for the 8.2m Subaru telescope is planned to employ 126 2k x 4k CCDs to cover a 1.5 degrees diameter field of view. This field of view is nearly ten times wider than the current prime focus camera, Suprime-Cam. The larger HyperSuprime must be designed to minimally impact the Subaru Telescope when installed. It should fit in the existing Inner-Hub and also the Top Unit Exchanger. The space and weight constraints are severe considering the tight optical tolerance. To achieve this, the we will adopt CFRP (Carbon Fiber Reinforced Plastic) for major mechanical structure.
