1. The chief scientist of Pingtang Astronomical Telescope is Nan Ren Dong, who is a researcher at the National Astronomical Observatory of Chinese Academy of Sciences.

The 500-meter spherical radio telescope (FAST) is one of the nine national science and technology infrastructures determined by the National Leading Group for Science and Education. It is planned to build a high-sensitivity giant radio telescope with the size of about 30 football fields by using the original design of China scientists and combining with the unique topographic conditions of karst depression in southern Guizhou. The chief scientist of this project is Nan Researcher of the National Astronomical Observatory of Chinese Academy of Sciences.

6. Awards and honors:

From 65438 to 0984, the active galactic nuclei were systematically observed and studied by using the international very long baseline network. In the early development stage of this field, he presided over more than ten observations on European and global networks. VLBI "snapshot" model was applied for the first time in the world, and rich astrophysical achievements were obtained. VLBI hybrid graph reached the highest dynamic range level in the world at that time. The establishment of domestic post-correlation image processing center made it possible to analyze China VLBI data in 1980s. His outstanding achievements over the years have been praised and recognized by international peers. In 2006, he was elected President of Radio Department of International Astronomical Society.

From 1994, it is proposed to build a giant spherical telescope as a unit of international SKA with karst depression as the telescope site, and the site selection began in Guizhou. 14 years as chief scientist and chief engineer, conscientiously presided over the establishment, feasibility study and preliminary design of the national major scientific and technological infrastructure construction project-500-meter spherical radio telescope FAST. Editor-in-chief of Scientific Objectives, directing key technology research and model test.

2. Introduction of Pingtang Astronomical Telescope

FAST is the most advanced project in the field of astronomical science in China, which uses natural karst potholes in Guizhou as the venue. 4,600 units are creatively laid in the pit to form a 500-meter spherical cap active reflector; The optical cable traction mechanism and parallel robot will be used for the first time to realize the high-precision positioning of the telescope receiver. In engineering technology, it not only inherits all possible advanced technical ideas at present, but also puts forward an innovative active reflector and photoelectric integrated feed support scheme, which greatly increases its receiving area. In addition, it simplifies the feed and its supporting system, and greatly expands the tracking range of FAST to celestial bodies and spacecraft.

The foundation stone of FAST project was laid on February 26th, 2008 +65438. It is expected to be completed in September 2065438+2006. After completion, compared with the arecibo radio telescope, the largest single aperture radio telescope in the world, it will bring more space for human beings to observe the universe.
