Prime Focus Spectrograph (PFS) for the Subaru telescope: ongoing integration and future plans
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 recently started undertaking the commissioning process of a subsystem at the Subaru Telescope side, with the integration and test processes of the other subsystems ongoing in parallel. We are aiming to start engineering night-sky operations in 2019, and observations for scientific use in 2021. This article gives an overview of the instrument, current project status and future paths forward.

© 2018 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 all the people involved with this PFS project in the past in various formats. Without their efforts and contributions, the project would not even start or continue to exist until 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 be sent to the staffs at Durham University in the United Kingdom, for their supports of the development of the PFS fiber system as the consultancy. 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.
