All fiber positioner modules were shipped

      Comments Off on All fiber positioner modules were shipped

It was April 2018 that the first fiber module was shipped from Caltech, US to Taiwan. Two years later, now we have completed delivering all the modules to Taiwan. PFS is an instrument to observe celestial objects using optical fibers. Actuators nicknamed “Cobras” are used to position fibers to the targets, and “Cobra” modules consisting of the “Cobras” and fibers… Read more »

      No Comments on The first Spectrograph Module is heading to Subaru

In October 2019, one of the PFS instrument subsystems, the first Spectrograph Module was shipped to Hawaii Observatory, National Astronomical Observatory of Japan. We obtain about 2400 spectra with four Spectrograph Modules. The Spectrograph Modules are being developed by Laboratoire d’Astrophysique de Marseille (LAM, France), Johns Hopkins University (the USA), Princeton University (the USA) and Laboratório Nacional de Astrofísica (Brazil). Since… Read more »

5 “Cobra Modules” left from California to Taiwan

      Comments Off on 5 “Cobra Modules” left from California to Taiwan

Among the PFS instruments, “Cobra” modules position fibers to galaxies and stars on the Subaru Prime Focal plane. 42 Cobra modules, each of which consists of 57 fibers and its positioners, cover the entire PFS field of view without any inaccessible gaps as shown in Figure 1. Two groups are collaborating to assemble “Cobra Modules”; Brazilian team responsible for fibers,… Read more »

Metrology Camera left Taiwan to Hawaii

      Comments Off on Metrology Camera left Taiwan to Hawaii

One of the PFS instrument “Metrology Camera” was finally shipped from Taiwan to Hawaii!! Metrology Camera  is an instrument used to measure the fibers position while we configure fibers to target objects. Academia Sinica Institute of Astronomy and Astrophysics (ASIAA) in Taiwan has the responsibility for Metrology Camera development, and they tested its performances before shipping in the last a… Read more »
