Announcement - 2015 WFOS-MOBIE Mini-studies Final Review

The Wide Field Optical Spectrograph (WFOS) is one of the three first-light observing capabilities selected by the TMT Science Advisory Committee. The Multi-Object Broadband Imaging Echellette (MOBIE) instrument design concept has been developed to address the WFOS requirements as described in the TMT Science-Based Requirements Document. As the name implies, WFOS-MOBIE is a seeing-limited, wide-field imaging multi-object echellette spectrograph. WFOS-MOBIE can directly image or create low (R = ~1000) to medium-resolution (R = ~8,000) spectra in two color channels simultaneously, spanning 310-550nm and 500-1100nm passbands respectively. WFOS-MOBIE views a rectangular field of approximately 3.0 arcmin x 8.3 arcmin resulting in a field area of 24.9 square arcminutes, and a total slit length of 500 arcsec.
The TMT partnership has been engaged in an effort to form a full WFOS team through an international workshare development process. A key step in this process was the submission of Expressions of Interest (EoIs) from various groups that are interested in contributing to the design and construction of WFOS. The institutions submitting these EoIs have been grouped into twelve “mini-study” teams to further investigate the most important aspects and subsystems of the instrument. The goals of these mini-studies were (i) to familiarize the teams with both the elements of WFOS-MOBIE and the TMT standards for instrument design studies, and also (ii) address a range of both technical and cost/schedule questions to support further progress on the WFOS-MOBIE design cheap viagra online uk.
This review is being held to assess the results of the WFOS-MOBIE mini-studies. These results include technical designs, engineering and performance analyses, cost/schedule estimates and management plans that may have a significant impact on the future development of WFOS. A second objective is to determine which teams have demonstrated a level of technical and management expertise consistent with what is required to be a successful partner in the WFOS team. Team members should be ready to “take ownership” of their contributions in terms of technical designs, performance requirements, error budgets, and schedule and cost estimates before proceeding further. A summary of the results of the meeting, including the recommendations from the review panel, will be presented to the TMT Instrumentation Department Head and, in turn, to the TMT Project Manager by the Decision Making Authority (Luc Simard). The TMT Project Manager will accept or augment the findings and recommendations and will seek the advice of the TMT SAC. The TMT Project Manager will report the process and results to the TMT Board seeking guidance as necessary.

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.

        此次实验,重在检验中科院理化所自主研发的全固态激光钠信标激光器原理样机的物理性能指标,能否满足下一代巨型望远镜TMT的多层共轭自适应光学(MCAO)系统的使用要求。为了达到实验目的,中科院国家天文台会同理化所、光电所和TMT项目总体部专家,自2010年起组成了联合实验组,开展了多年的分工协作。TMT总体部负责TMT/MCAO系统对钠信标激光器的技术指标论证;国家天文台负责实验平台建设以及实验数据的分析和仿真模拟;理化所负责激光研制的技术攻关;光电所负责激光器发射装置(LGSF)的研发。联合实验组曾于2011年,2013年先后在云南丽江,加拿大温哥华UBC大学LZT天文台进行了前期外场实验,都成功获取相关实验数据。此次兴隆实验,是对钠激光器原理样机性能否满足TMT 30多项技术指标要求的全面检验,诸多国内外专家都十分期待实验结果。



The Thirty Meter Telescope (TMT) is no longer a distant future. China, through NAOC, has joined the TMT as a founding partner, and ground-breaking for the TMT project began in October 2014.  When completed, the TMT will be one of the most powerful telescopes in the history of astronomy, and it will be one of the greatest astronomical facilities that 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.

The theme of this year's KIAA-PKU Astrophysics Forum, held on November 2-4, 2014, is "Thirty-Meter Telescope in China: Scientific and Technological Frontiers". The meeting is jointly organized by KIAA and NAOC.  Participants include academician Chen Jiancheng, academician Cui Xiangchun, NAOC director Yan Jun, NAOC vice directors Zhao Gang and Xue Suijian.  The opening ceremony was attended by Peking University President Wang Enge and NSFC/DMPS vice director Dong Guoxuan.  Opening remarks were given by KIAA Director Luis Ho, PKU President Wang Enge, Academician Chen Jiansheng, and NAOC Director Yan Jun.   In total, there were over 120 participants from 26 institutions and universities in China.  A broad range of technical and scientific topics were covered, including the TMT and its connections to other large facilities, China's involvement in instrumentation related to TMT, cosmology, galaxy formation and evolution, active galactic nuclei and black hole physics, stars and stellar systems, and extrasolar planets.  

In addition to scientific presentations, there was time allocated for detailed discussion of short-term and long-term strategies in developing optical and infrared astronomy in China. The participants reached the following consensus.  One one hand, we need to do the research and get the community trained to use currently available domestic and international observing facilities. On the other hand, we need to accumulate the necessary experience and advantages in technology and science by joining the international collaborations including TMT, and be well prepared for building the big domestic facilities in the future. 


举 世瞩目的30米望远镜(TMT)的建成离我们已并不遥远。中国科学院国家天文台已代表中国天文界加入TMT国际合作计划,并成为30米望远镜国际天文台 (TIO)创始伙伴之一。TMT国际合作计划目前的参与国家有美国、加拿大、日本、中国和印度。今年10月,TMT已在夏威夷莫纳克亚山顶开始动工建设。 一旦建成,它将成为世界天文史上最具威力的大天文设备之一。作为在21世纪初期中国天文学家能使用的一台极大望远镜,它将给中国天文界带来前所未有的发展 机遇。如何在科学和技术上做好必要的准备以便利用TMT获得最大的科学产出已成为中国天文界目前面临的巨大挑战。

本年度科维理-北京大学 天体物理论坛于2014年11月2-4日在北京大学举行,会议主题为“30米望远镜在中国:科学与技术前沿”。本次会议由北京大学科维理天文与天体物理研 究所和中国科学院国家天文台联合举办。北京大学校长王恩哥院士、北京大学天文系首任系主任陈建生院士、南京天文光学技术研究所前所长崔向群院士、国家天文 台台长严俊、党委书记赵刚、国家自然科学基金委数学物理科学部副主任董国轩、科维理天文所所长何子山、国家天文台副台长薛随建、中国三十米望远镜项目科学 家毛淑德等出席了开幕式。何子山所长、王恩哥校长、陈建生院士和严俊台长分别致开幕辞,祝愿本届论坛成功举办,并对三十米望远镜项目表示支持。来自国内 20多个研究所和大学的120余名天文学家和工程师参加了本次会议,并对TMT相关的技术和科学议题进行了广泛而深入的交流。会议内容包括:三十米望远镜 与其他未来的大型天文望远镜之间的协同合作;中国在三十米望远镜仪器开发中的技术创新与突破;三十米望远镜在宇宙学、星系形成与演化、活动星系核与黑洞物 理、恒星与恒星系统、太阳系外行星研究中所能实现的科学目标等。

除科学与技术报告外,会议还安排了对中国光学和红外天文短期和长期发展战 略的仔细讨论。大家一致认为,一方面我们需要利用国内现有设备和申请利用国际观测设备来开展科学研究和培养观测天文学家,另一方面我们需要借助参加TMT 等国际合作来积累技术和科学上的经验和优势,为以后在国内自主建设大天文设备打下基础。
