我们介绍了东京大学阿塔卡马1.0米望远镜的现状，该望远镜建于智利阿塔卡马Chajnantor公司的顶峰（5，640米），这是世界上最高的光学/红外望远镜。该望远镜是f/12 Ritchey-Chretien型，视场为10弧分。它安装在一个6米的圆顶内，并在与圆顶分开的容器中从操作室进行控制。2009年3月进行了工程首次灯光观测，2009年6月开始进行天文观测。望远镜的指向精度为2.4弧秒（RMS），显示出良好的跟踪精度为0.2弧秒60秒的观察没有指导。哈特曼常数为0.19角秒，望远镜的图像质量对于科学观测来说是令人满意的。最佳点扩展函数在光学上为0.5弧秒（半高宽），这表明Chajnantor山顶是世界上最好的景点之一。利用ANIR近红外相机和MAX 38中红外仪器进行的成功观测也证明了该站点在红外波段具有良好的大气透射性。在不久的将来，手术室将与圣佩德罗德阿塔卡马的基地支助设施连接，以便进行远程观察。
We present the current status of the University of Tokyo Atacama 1.0-m telescope constructed at the summit of Co. Chajnantor (5,640 m) in Atacama, Chile, which is an optical/infrared telescope at the world's highest site. The telescope is an f/12 Ritchey-Chretien type with a field of view of 10 arcmin. It is installed in a 6-m dome and is controlled from the operation room in a container separated from the dome. The engineering first light observation was carried out in March 2009, and the astronomical observations have been carried out since June 2009. The pointing of the telescope is as accurate as 2.4 arcsec (RMS), showing good tracking accuracy of 0.2 arcsec for 60-s observation without guiding. The Hartmann constant is 0.19 arcsec and the image quality of the telescope is satisfactory for scientific observations. The best PSF obtained is 0.5 arcsec (FWHM) in optical, which demonstrates that the summit of Co. Chajnantor is one of the best seeing site in the world. Also the excellent atmospheric transmission in infrared wavelength at the site is proved by successful observations carried out by the ANIR near-infrared camera and the MAX38 mid-infrared instrument. In the near future, the operation room will be connected to the base support facility at San Pedro de Atacama for remote observation.
