Abstract

The next generation wide field camera HSC (Hyper Suprime-Cam) on Subaru telescope is planned to cover 1.5 degree diameter field with a focal plane size about 650mm. To minimize the impact to the telescope, the design for the elements of the camera is constraint to the tight space and weight limits. In order to fit the available space, the screen winding shutter and petal shape filter exchanger are designed for the HSC. The CFRP is used for the structure to minimize the load. In this report, the design and analysis for the shutter and filter exchanger system will be presented. The result for the shutter membrane tests will also be discussed.
