摘要

We describe the conceptual design of the camera cryostats, detectors, and detector readout electronics for the SuMIRePrime Focus Spectrograph (PFS) being developed for the Subaru telescope. The SuMIRe PFS will consist of fouridentical spectrographs, each receiving 600 fibers from a 2400 fiber robotic positioner at the prime focus. Eachspectrograph will have three channels covering wavelength ranges 3800 Å - 6700 Å, 6500 Å - 10000 Å, and 9700 Å -13000 Å, with the dispersed light being imaged in each channel by a f/1.10 vacuum Schmidt camera. In the blue and redchannels a pair of Hamamatsu 2K x 4K edge-buttable CCDs with 15 um pixels are used to form a 4K x 4K array. Forthe IR channel, the new Teledyne 4K x 4K, 15 um pixel, mercury-cadmium-telluride sensor with substrate removed forshort-wavelength response and a 1.7 um cutoff will be used. Identical detector geometry and a nearly identical opticaldesign allow for a common cryostat design with the only notable difference being the need for a cold radiation shield inthe IR camera to mitigate thermal background. This paper describes the details of the cryostat design and coolingscheme, relevant thermal considerations and analysis, and discusses the detectors and detector readout electronics.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
