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!

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, the hatch has been installed, the crane has been accommodated in the room, and the clean room has been constructed. Currently, further preparations are going on to receive the PFS spectrographs such as  piping  cooling systems and cabling power distribution.

Besides, in September 2017, a rack to accommodating devices to control the spectrographs and the clean room was delivered to the Subaru Telescope, from Johns Hopkins University.


A rack for control systems settled nearby the clean room.

The control devices will be installed to the rack soon, and then some experiment will be carried out for controlling the room temperature.


2017年7月、すばる望遠鏡ドーム4階に分光器設置室 がついに完成しました!

PFSの分光器4台を設置する為に、これまで使用されていた装置をドーム棟4階から片付けてから1年余り。床の補強、ハッチ扉の設置、室内クレーンの設置などを経て、分光器設置室の建設が終了しました。現在は冷却系統の設置や、電気配線など、分光器を迎える準備がさらに進んでいます。

また、2017年9月には分光器や分光器設置室の制御デバイスが入るラックがジョンズ・ホプキンス大学からすばる望遠鏡へ到着しました。

今後は制御用ラックにパソコンなどが取り付けられ、設置室の温度管理試験などが行われていく予定です。
