摘要
中国科学技术大学-中国科学院紫金山天文台2.5米大视场巡天望远镜(即墨子巡天望远镜,WFST)是中国科学技术大学“双一流”学科平台建设项目,双方于2018年3月1日召开望远镜项目预研启动会,2019年7月正式开展望远镜建设,2023年8月望远镜建成并开展调试观测,2023年9月17日望远镜首光仪式暨科学战略研讨会召开,并成功发布仙女座星系图片,标志着望远镜设备基本达到设计标准,已经可以开展天文观测研究。墨子巡天望远镜口径2.5米,采用国际先进的主焦光学系统设计和主镜主动光学矫正技术,可实现3度视场范围内均匀高像质和极低像场畸变成像,配备7.65亿像素大靶面主焦相机,具备大视场、高像质、宽波段的特点。墨子巡天望远镜安置于青海省海西州茫崖市冷湖镇赛什腾山海拔4200米的天文台址,是冷湖天文观测基地首个投入运行并开展天文观测研究的大型设备。墨子巡天望远镜通过获取天体高精度位置和多波段亮度观测数据,监测移动天体和光变天体,高效搜寻和监测天文动态事件,可以在高能时域天文、太阳系天体普查、银河系结构和近场宇宙学等研究领域取得突破性原始创新成果。同时,墨子巡天望远镜将面向国家航天强国战略,开展太阳系近地天体等搜寻与监测研究,服务航天安全和深空探测战略需求。
The University of Science and Technology of China(USTC)-Purple Mountain Observatory(PMO)2.5-meter Wide Field Survey Telescope(Micius Survey Telescope,or WFST)is a“double first-class”discipline platform construction project of USTC.The two parties held a preliminary research kick-off meeting for the telescope project on March 1,2018.The construction of the telescope was officially launched in July 2019.The telescope was installed and commissioned in August 2023.The telescope first-light ceremony and scientific strategy conference were held on September 17,2023,and pictures of the Andromeda Galaxy were successfully released.The telescope and camera have reached the design standards and are ready to carry out astronomical observations.The Micius Survey Telescope has an aperture of 2.5 meter.It adopts an advanced prime-focus optical system design and primary mirror active optical correction technology to achieve the uniform high quality and extremely low distortion imaging capability within a 3-degree field of view.It is equipped with a 765 million pixel mosaic CCD detector.It has the characteristics of large field of view,high image quality,and wide waveband coverage.The Moicius Survey Telescope is located on the summit of Saishiteng Mountain,Lenghu Town,Qinghai Province,China.It is the first large-scale facility in operation at the Lenghu Astronomical Observatory.By acquiring high-precision astrometry and high sensitivity multi-band photometry for celestial objects repeatedly over large sky area,the Micius Survey Telescope can monitor moving celestial objects and light-varying sources,and can be used to efficiently search and monitor astronomical dynamic events.The time-domain survey will provide big data for achieving scientific breakthroughs in the areas of time-domain astronomy,solar system objects,the Milky Way structure and near-field cosmology.At the same time,the Micius Survey Telescope will be oriented towards the national space power strategy,carries out search and monitoring researches on near-earth objects in the solar system,and serves the strategic needs of space security and deep space exploration.
