title = "Software development of fiber positioning sequencer for prime focus spectrograph of Subaru telescope",
abstract = "The Prime Focus Spectrograph (PFS) is a new optical/near-infrared multi-fiber spectrograph designed for the prime focus of the 8.2m Subaru telescope. PFS will cover a 1.3-degree diameter field with 2394 fibers to complement the imaging capability of Hyper SuprimeCam (HSC). The Fiber Positioning System (FPS) is an automated system that controls the sequences for the operation of the PFS subsystems to achieve accurate positioning of the science fibers for astronomical observations. FPS will be operated continuously for 14 hours a night and accomplish the fiber positioning sequence every 15 minutes. The success rate of each alignment should be 95% or more and FPS should finish the fiber alignment procedure in 105 seconds. A fast centroid algorithm is implemented for measuring 2349 fiber spots within 1 second. In this report, the latest status of the development of FPS system will be given, including the system performance and closed-loop simulations.",
