I'm sorry for not having enough details,the rings took too many parts.

About this model:
G1 to show the linear accelerator.
G2 for the enhancer.
G3 is the track for electrons to radiate synchrotron radiation and storaging electrons.


About the facility:
The Shanghai Synchrotron Radiation Facility (SSRF)is a synchrotron-radiation light source facility in Shanghai, People's Republic of China. Located in an eighteen-hectare campus at Shanghai National Synchrotron Radiation Centre, on the Zhangjiang Hi-Tech Park in the Pudong district.

SSRF is operated by the Shanghai Institute of Applied Physics (SINAP). The facility became operational in 2009, reaching full energy operation in Dec 2012.

It has a circumference of 432 metres, and is designed to operate at 3.5 GeV, the highest energy of any synchrotron other than the Big Three facilities SPring-8 in Hyogo Prefecture, Japan, ESRF in Grenoble, France and APS at Argonne National labs, United States. It will initially have eight beamlines.

The particle accelerator cost 1.2 billion yuan (US$176 million). It is China's biggest light facility.It is located under a building with a futuristic snail-shaped roof.

The synchrotron opened to universities, scientific institutes and companies for approved research in May 2009.
