Bureau of Basic Research and Bureau of Comprehensive Planning of Chinese Academy of Sciences (CAS) arranged an Expert Test Group for the locale test of the LAMOST Project in Xinglong Observatory, National Astronomical Observatories (NAOC) from Dec.15 to Dec.18 2008 meanwhile an Appraisal Acceptance Expert Group was arranged for LAMOST technics appraisal acceptance on Dec.19 2009。
The Appraisal Acceptance Expert Group includes 17 experts such as Academician Shuhua Ye, Academician Jiaqi Wang, Academician Wenlong Zhan, Academician Jiansheng Chen, Academician Nenghong Zhu, and among them Ye and Wang are the group leader and vice group leader respectively。
The Appraisal Acceptance Expert Group checked LAMOST engineering locale and the related technical documents very carefully, and listened to the Manufacturing Technical Report by General Engineer Prof. Xiangqun Cui of the LAMOST Project。
Furthermore they also listened to the LAMOST locale Test Report by the Expert Test Group Leader Academician Jiaqi Wang before their deliberation。
The Appraisal Acceptance Expert Group came to believe that LAMOST has broken through the difficulty of optical telescopes having both large aperture and large field of view, and realized active optics technology on both the Primary Mirror and the Schmidt Mirror by real-time perfect segmentation of several tens of thin deformable sub-mirrors, and made a survey and evaluation of 4000 objects by the 4000 fibers in the field of view。
LAMOST is the large Schmidt telescope with the largest aperture, the largest field of view and the highest spectrum obtaining rate in the world, and it is approved by the international colleagues.
LAMOST has many technology innovations during the manufacturing and it lays a solid foundation for the future development of even larger telescope。
According to the requirements ratified by the State Development and Reform Commission(SDRC), the Expert Group all agreed that the optical quality of LAMOST is much better than project specification, the pointing and tracking accuracy of LAMOST, positioning precision of 4000 fiber units are all better than task requirements, the multi-object spectroscopic subsystem consisting of 4000 fiber units, 16 spectrographs and 32 CCD cameras works properly, the fiber light transmission rate is better than 99%。
The LAMOST construction has been completely finished with high quality, and all devices work well。
The LAMOST project is advised to be submitted for State appraisal。In considerations of the advanced technology and complicated system of LAMOST, the Expert Group also suggested to reinforce and make perfect the Management team, Running team and Support system as soon as possible to bring its benefit into full play and better realize scientific goals。
