The prototype fiber cable has been installed on the telescope/ 試作ファイバーケーブルを望遠鏡に敷設

We reported that Metrology Camera System had been installed to the Subaru Telescope for the test. MCS, however, is not the only instrument for PFS to have been installed to the telescope. The prototype fiber cable was also routed on the telescope to test the optical performance about a half year ago. The work was done a little long time… Read more »

After the arrival of metrology camera at the Subaru telescope… / すばる望遠鏡到着後メトロロジカメラは…

Since we published the article about the delivery of the Metrology Camera System (MCS) to Subaru Telescope in May this year, the member mainly from ASIAA (Academia Sinica Institute of Astronomy and Astrophysics, Taiwan) have visited Subaru Telescope a few times, in order to finalize the integration and proceed the on-site tests. In this article, we are going to talk… Read more »

Metrology Camera is at Subaru Telescope Now! / メトロロジカメラ、すばる望遠鏡へ到着

About one month has passed since Metrology Camera was shipped from Taiwan. Now it has arrived at Subaru Telescope at Maunakea in Hawaii. After shipping, from 23 April 2018, members from Academia Sinica, Institute of Astronomy and Astrophysics (ASIAA) visited to Hawaii Observatory of National Astronomical Observatory of Japan for final development. At Hilo base, ASIAA inspected Metrology Camera and… Read more »

The first things installed at the Subaru telescope is … / すばるに設置された一番乗りは…

The subsystems of the PFS instrument are being developed at various institutes. These subsystems will be delivered to the Subaru telescope in Hawaii from what will be finished integration and test at the laboratory. It is already one year before the first subsystem will be delivered to the Subaru telescope, and start its integration and test there. To operate the… Read more »

Subaru renovated a dome floor for the PFS Spectrographs / 分光器設置室完成

In July 2017, the Spectrograph Clean Room  was finally built up on the fourth floor of the dome building at Subaru Telescope! Spectrograph Clean Room at Subaru Telescope It has been one year and a few month since the previous instrument was cleaned up from the floor, in order to accommodate four PFS spectrographs. Since then, floor has been reinforced,… Read more »

Installation of Spectrographs Clean Room Crane / 分光器設置室用クレーン設置

The integration of the Spectrographs Clean Room has been progressing at the Subaru Telescope observatory since last May, when the floor of the dome building was cleaned up. Recently, a crane has been installed to the ceiling structure of the spectrograph floor. This 500kg-capacity crane will be used to carry the individual components and sub-assemblies of the spectrograph module such… Read more »

Renovation for the PFS spectrograph system / PFS分光器システムを迎えるために…

The PFS spectrograph system, consisting of four identical modules, will be accommodated in a designated clean room on the fourth floor of the Subaru telescope enclosure building. Envisioning the delivery of the first modules in 2017, we have been developing the design and implementation plan of the floor and clean room. After we had a design review meeting in August… Read more »

Network Connection Test at Subaru Telescope / すばる望遠鏡でネットワーク通信試験をしました

Subaru Telescope, where PFS will be installed, has been used for cutting-edge researches in astronomy and astrophysics since 1999 when it started its science operation. Because we will install a brand-new, state-of-the-art instrument on the more than 15-years old telescope, we sometimes run into difficulties due to “generation gap”. Today we will talk about network connection, one of many such… Read more »
