Prime Focus Spectrograph (PFS) for the Subaru Telescope: Overview, recent progress, and future perspectives
Abstract
PFS (Prime Focus Spectrograph), a next generation facility instrument on the 8.2-meter Subaru Telescope, is a very wide-field, massively multiplexed, optical and near-infrared spectrograph. Exploiting the Subaru prime focus, 2394 reconfigurable fibers will be distributed over the 1.3 deg field of view. The spectrograph has been designed with 3 arms of blue, red, and near-infrared cameras to simultaneously observe spectra from 380nm to 1260nm in one exposure at a resolution of ~1.6-2.7Å. An international collaboration is developing this instrument under the initiative of Kavli IPMU. The project is now going into the construction phase aiming at undertaking system integration in 2017-2018 and subsequently carrying out engineering operations in 2018-2019. This article gives an overview of the instrument, current project status and future paths forward.

© 2016 Society of Photo-Optical Instrumentation Engineers (SPIE). We appreciate all the contributions from the PFS science team to the instrument requirements definitions and the survey planning. We also thank the people involved with this PFS project in the past in any formats. Without their efforts and contributions, the project would not even exist now. We are grateful to the staffs (in addition to those on the author list) at National Astronomical Observatory of Japan and the Subaru Telescope observatory for their contributions to the development of the PFS instrument, the modifications of the telescope system and other infrastructures to accept PFS, the preparations of PFS system integration and engineering observations, and various other aspects such as the administrative supports. Our thanks should also go to the staffs at Durham University, UK, for their supports of the development of the PFS fiber system as the consultancy. We are grateful to the external reviewers at the PFI critical design review (Kim Aaron, Mark Colavita, Randy Foehner, Kirk Seaman from JPL, French Leger from University of Washington, and Ted Huang from ASIAA) for their insightful and valuable inputs. We gratefully acknowledge support from the Funding Program for World-Leading Innovative R&D on Science and Technology (FIRST) program "Subaru Measurements of Images and Redshifts (SuMIRe)", CSTP, Japan.
