科研費特定領域研究「マゼラン星雲大研究」の計画研究に
基づき、名古屋大学、国立天文台、名古屋市立大学が中心と
なって開発を進めてきた観測装置SIRIUSが、2000年8月10日
ハワイ大学2.2m望遠鏡にて無事ファーストライトを迎えました。

SIRIUSは、1024x1024素子HgCdTeアレイを３基搭載し、
近赤外のJHKs３バンドを同時撮像することのできる
強力な赤外線カメラです。

すばる望遠鏡ハワイ観測所スタッフと関係者のみなさまと、
Adrew Pickles氏をはじめとしたハワイ大学スタッフのみなさま
には、今回さまざまなサポートをしていただきました。
光学系の基本設計については山室智康氏に、クライオスタット
製作については河合利秀氏に、温度コントローラについては
禅野孝弘氏に、真空冷却モーターについては渡邊誠氏に、
それぞれ大変お世話になりました。
ここに厚くお礼申し上げます。

Dear All,

We are pleased to announce that the infrared astronomical
instrument "SIRIUS", which has been developed
under the collaboration between Nagoya University,
NAOJ, NCU, and others for the last two years, has obtained
its first light on the UH 88 inch telescope on August 10, 2000.

SIRIUS, employing three science-grade Rockwell 1024x1024 HgCdTe
arrays, can simultaneously image the same field of view
(5'x5' on UH88) in three bands at near-infrared wavelengths
(J, H, Ks bands).

Please take a look at the SIRIUS home page
http://www.z.phys.nagoya-u.ac.jp/sirius/index.html
for the first light (FL) images and instrument details.

We, SIRIUS development team, thank the Subaru Telescope
staff and the other related people for their support and
encouragement of this project. We also thank the UH staff,
in particular Adrew Pickles, for their support of this
first light run. Special thanks to Yamamuro-san for his
excellent optical design as demonstrated with this run,
Kawai-san for his help in making cryostat, Zenno-san for
his temperature controller, and Watanebe-san for his help on
cryogenic motors and mechanical design.

First light team members
(and short introduction to students and PDFs)
are:

NAGASHIMA Chie (NU, D2: croystat and optics)
- SIRIUS's compact and robust cryostat is her hand-made!

NAGAYAMA Takahiro (NU, D1: array control)
- SIRIUS is a first system with Messia IV and MACS.
Its usability is shown by him with this run.

NAKAJIMA Yasushi (NU, PDF: reduction software)
- The beautiful FL images on the Web are from his fingers!

NAKAYA Hidehiko (NAOJ, PDF: array electronics)
- You know his great contributions to Messia IV and MACS.

and some older(?) people are

SUGITANI Koji (NCU, AP: reduction software)

TAMURA Motohide (NAOJ, AP: SIRIUS project PI)

in collaboration with
the SA 1.4m group headed by Prof. S. SATO (NU) and
T. NAGATA (NU), T. HIRAO (NU), M. HAYASHI (NAOJ),
Y. NAKATA (UoT), T. TANABE (UoT),
K. YANAGISAWA (OAO), and grad. students:
Oasa-san (UoT) and Matsumoto-kun (UoT)
