Feed Cabin Installation of World's Largest Radio Telescope Completes in Southwest China

The installation of the feed cabin of China's single-aperture spherical telescope "FAST" in Pingtang county, southwest China's Guizhou Province was completed on Friday, meaning the telescope is ready to function. After the installation was completed, the 30-ton-heavy feed cabin, the core part of FAST, was hoisted up to 130 meters above the telescope’s reflector which is the size of 30 football fields. The cabin is home to a feed source which collects signals from the universe. "It is the receiver of the FAST and the receiver is the most important part. It receives all the signals collected by FAST. It's as important as the apple of the eye," said Zheng Xiaonian, deputy head of National Astronomical Observatories of China (NAOC). The feed cabin will be driven by cables and servomechanisms in addition to a parallel robot as a secondary adjustable system to move with high precision. "We haven't done tests with all the systems ready. Now most of the systems are ready for joint tests. We can do some tests after the feed cabin is hoisted up and can receive some scientific data," said Yue Youling, assistant research fellow at the science department of FAST. Friday's work marked the completion of the 500-meter aperture spherical telescope (FAST) which will be the world's largest, overtaking Puerto Rico's Arecibo Observatory, which is 300 meters in diameter. The telescope has now entered the phase of all-system debugging and has started to receive signals of pulsars. More on:http://www.cctvplus.com/news/20160917...
