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.

TIPC Laser Prototype Feasibility Review

TIPC Laser Prototype Feasibility Review will be hold on Jan 13-14,2015. Based on the results of the pulsed laser prototype laboratory tests and on the results reported for the on-sky tests, the commitee will review the performance of the TIPC pulsed laser prototype to see if it meets the TMT performance requirements and if TIPC laser is the credible solution for TMT. The detailed objectives include: 1) to understand the design of the laser and overall risks associated with the design; 2) to understand the strength and weakness of the laser for long term operation for an astronomical observatory science program and under the environmental conditions of an astronomical observatory; 3) to review the current and subsequent stages in the development of the TMT laser system including the main tasks to be performed, risks, schedule, and budget; 4) to understand the plan for developing the complete TMT Laser System, and the risks associated with this design.
This meeting is hosted by National Astronomical Observatories and Technological Institute of Physics and Chemistry, Chinese Academy of Sciences.

TMT in China: Scientific and Technological Frontiers

With the construction to start imminently in October 2014, the Thirty Meter Telescope (TMT) is no longer a distant future. TMT will be one of the most powerful telescopes in the history of astronomy, and it will be one of the greatest astronomical facilities China will possess in the beginning of the 21st century. It will bring unprecedented opportunity to Chinese astronomy. How to achieve scientific and technical readiness for TMT to maximize its impact is a great challenge that the Chinese astronomy community is facing.

We set the theme for this year's KIAA-PKU Astrophysics Forum to discuss the scientific and technological frontiers of the TMT. On the one hand, the conference plans to offer prospects on how Chinese astronomers can make potential breakthroughs in astrophysics frontiers.  Participants will discuss how to organically relate their short-term research with the long-term goals relevant to TMT The conference will cover diverse fields, including cosmology, galaxy formation and evolution, active galactic nuclei and black hole physics, stars and stellar systems, and extrasolar planets.  We will also discuss the coordination between TMT and other large astronomical projects in China, in order to maximize their scientific impact and enhance China's capacity in astronomy across the full spectrum. On the other hand, the conference will discuss China's technological involvement in the TMT. Scientists and engineers will meet under the same roof to discuss how to finalize the TMT instrument specifications in order to optimize for the science objectives as well as reach deeper a understanding of the instruments to plan and design better science projects.

We invite broad participation from the entire astronomical community in China.
