三十米望远镜国际天文台(Thirty-Meter-Telescope International Observatory)

非盈利的TMT天文台公司成立于2003年6月。TMT源于三个较早的大型望远镜项目的合并,即加利福尼亚极大望远镜(CELT)、甚大光学望远镜(VLOT)和巨形拼接式镜面望远镜(GSMT)。
 
这些独立的项目目标近乎一致,即整合现今领先天文台运转经验,推动尖端技术的发展,拓展现有先进设施亦无法实现的天文学研究领域。
 
2003年,TMT召集了“科学顾问委员会”,成员包括其合作机构及更多科学界人士,来帮助TMT打造与下一代天文台需求相匹配的技术能力。
2014年5月6日,TMT国际天文台有限责任公司(TIO)成立,初始成员包括:

  • 美国加州理工学院
  • 日本国家自然科学研究所
  • 中国科学院国家天文台
  • 美国加州大学董事会 

         TIO负责TMT设计、开发、建造和运转。
2014年5月,加拿大大学天文学研究协会与印度天体物理学研究所作为合作机构加入,积极为TMT提供实物支持。另外,大学天文学研究协会也作为合作机构加入。
2014年12月,印度天体物理学研究所成为TMT国际天文台的正式成员。2015年4月,加拿大也作出相关承诺,并在2015年6月被选为全面合作伙伴。

Thirty Meter Telescope-MICHI and China: A workshop on thermal-IR astronomy

On July 16, 2018, a workshop about TMT-MICHI was held in National Astronomical Observatories, CAS (NAOC), Beijing.  
 
MICHI stands for Mid-IR Camera, High-disperser & IFU spectrograph. This workshop focused on ground-based thermal-IR science that can be done now and the science cases for building a thermal-IR instrument for TMT, harnessing expertise across the TMT partnership.  At this workshop, scientists and engineers discussed the goals and requirements of a thermal-IR instrument from the Chinese TMT community and discuss how our cross-TMT partnership can be leveraged into collaborations to pursue science goals now on existing instruments.  
 
Prof. Chris Packham (UTSA & NAOJ), Mitsuhiko Honda (Kurume University, Japan), Prof. Gregory Herczeg (PKU, China), Prof. Lei Hao (SHAO, China), TMT-China office and about 20 other Chinese Astronomers and engineers attended the meeting.

长春光机所TMT三镜系统研发团队获国家重点研发计划政府间国际科技创新合作重点专项支持

        近日,中国科学院长春光学精密机械与物理研究所(以下简称长春光机所)张学军研究员和杨飞副研究员带领的TMT专项团队获得国家重点研发计划政府间国际科技创新合作重点专项——TMT巨型可控科学反射镜关键技术合作研究(2017YFE0102900)的支持。
        我国在积极参与国际大科学工程——三十米望远镜(TMT)的过程中,由中国科学院国家天文台牵头组成TMT-中国团队,集成国内最具优势的技术团队,与国际先进技术团队开展实质性的国际合作。其中长春光机所负责研发TMT中相对独立的子系统——第三镜全系统。TMT三镜系统由于其独特的功能特性和几何尺寸,被赋予“巨型可控科学反射镜”之名。它将以3.594m×2.536m×0.1m几何尺寸成为世界上最大的椭圆形平面镜,并将是第一个在如此大的几何尺寸下具备二维指向可控的反射镜。
        长春光机所以国家重大需求为引导,瞄准国际前沿技术领域,将大口径光学工程技术列为所“一四六”计划中的四大重点突破技术之一,并自筹资金,于2013年组建TMT专项团队,积极参与国际大科学工程TMT建设,与国际先进的研制大口径望远镜的技术团队建立了良好的合作基础,培养和锻炼了一支面向世界科技前沿的青年技术团队,为自主研制大型光学红外望远镜奠定了人才基础,并带动了相关技术的进步,已获得多项国家自然科学基金的资助。
        此次获得国家重点研发计划政府间国际科技创新合作重点专项 (2017YFE0102900)的支持,是对长春光机所TMT专项团队前期工作的充分肯定,更是对TMT专项团队开展后续国际合作、深入研发相关关键技术的鼓舞。在国家重点研发计划的支持下,TMT专项团队将在项目执行周期内,通过与TMT国际天文台(TIO)的深入合作,开展针对TMT三镜系统的系统性能评价方法、面形精度评价与检测、系统刚度分配与检测、系统抖动误差测量与抑制等关键技术的研究,旨在解决大口径高分辨率望远镜研制过程中所面临的相关科学问题,突破大口径高分辨率望远镜研制的关键技术,为我国自主研制大型光学红外望远镜奠定技术基础。

TMT WFOS China Partnership Meeting

Beijing, China (October 16, 2017) – Representatives from the Thirty Meter Telescope’s (TMT’s) Wide-Field Optical Spectrograph (WFOS) team and TMT’s China partners gathered recently in China to discuss potential collaboration during the next stage of the conceptual design of WFOS.

 

WFOS is planned to be one of TMT’s first-light instruments. It will offer extraordinary new capabilities to study the early, distant universe, including the first stars and galaxies, and the intergalactic medium.

 

WFOS is now in its conceptual design phase, studying two different instrument designs: a slicer-based concept, and a fiber-based concept. The final decision will be made in March 2018. The next step will then include optimizing and prototyping the opto-mechanical design, fiber or slicer concepts, cameras, dispersive architecture, large refractive gratings, dichroics, robotics systems, and details of detector design. This will be followed by a two-year preliminary design phase, then final design, fabrication and integration and test phases, prior to fielding and commissioning on the telescope.

 

Dr. Fengchuan Liu, the Deputy Project Manager of TMT, updated the current status of TMT to all attendees remotely. WFOS Instrument Project Manager Maureen Savage (UCO), Lead Engineer Matthew Radovan (UCO) and Dr. Zheng Cai (UCO) introduced the program, the technical opportunities and the science goals of WFOS, respectively.

 

Representatives from several Institutes of Chinese Academy of Sciences and universities introduced their interests and their corresponding abilities, including National Astronomical Observatories of China (NAOC) and its affiliate, Nanjing Institute of Astronomical Optics & Technology (NIAOT); Shanghai Astronomical Observatory (SHAO); Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP); Shanghai Institute of Optics and Fine Mechanics (SIOM), University of Science and Technology of China (USTC); Shanghai Jiao Tong University (STJU); Huazhong University of Science and Technology (HUST); Beijing Institute of Technology (BIT).

 

The TMT WFOS delegation also visited SHAO, SIOM, NIAOT, USTC and Tsinghua University, and held face-to-face discussions with each team.
