China news agency, Beijing, February 7 (Reporter Zhang Su) - Observatory, Chinese Academy of Sciences said Wednesday that China 500 meters Aperture Spherical radio Telescope (FAST) successfully completed the manufacture and installation of the cable network, enter the reflective surface machining and assembly stage unit All installation and testing work will be completed before September 2016.
Chinese Academy of Sciences, chief scientist at the National Radio Observatory, Department of Li 菂 said, FAST is the caliber of the largest and most powerful single-antenna radio telescope being built in the world, receiving area approximately equal to 30 football fields. Upon completion, FAST will remain a world-class status in the next 20 years.
The main goal of FAST is to probe the universe distant signals and substance, in carrying out the origin of the universe to explore interstellar material structure of faint pulsars and other faint radio sources in the search, high efficiency to carry out aspects of the search for extraterrestrial rational life, etc. to achieve major breakthroughs in science and technology.
Cable net structure is the main support structure FAST initiative reflective surface. It is understood that, FAST cable net manufacturing and installation project was successfully completed on February 4, which is the world's largest span, highest precision cable net structure, but also the world's first a way of working with variable bit cable net.
Experts here, FAST cable net structure 500 meters in diameter, the entire cable net total of 6670 main cable, capturing the large span cable network installation design, high performance cable structure developed fatigue, ultra-precision manufacturing processes and other cable structures form the 12 independent innovation of patent results.
FAST's most prominent feature is the cable network structure can be changed automatically with the movement of celestial bodies, led 4450 online activities reflective panel cable change. Development work reflecting surface machining and assembly unit, feed tanks and tanks parked platforms by China Electronics Technology Group The company contracting.
China Electric Division panel unit 郑元鹏 technical director revealed that the reflective surface unit triangle, depending on the location, its geometry, tilt angle, not the same supporting point position, load size and direction, '4450 side in reflective surface unit types from 10.2 to 12.4 meters between the nearest 400 kinds.
Zhengyuan Peng said that they will be based on the installation requirements and coordinate data cable network node unit, using parametric design method, the surface of the sub-unit control precision of 1 mm or more, 'Let each one reflecting surface can focus, FAST and known Compared to 'ground largest machine' in Bonn, Germany 100 m telescope, the sensitivity increased by about 10 times. 'It is reported that the first piece of the panel is expected to be off the assembly line in May of this year.
