The Institute of High Energy Physics under the Chinese Academy of Sciences said Sunday China's spallation neutron source, one of the country's most important scientific facilities in Dongguan, South China's Guangdong province, has passed assessment and checks by the CAS.

The spallation neutron source is the first of its kind in the country and the fourth worldwide and will provide intense pulsed neutron beams for scientific research. It is a significant step in the country solving problems on the frontier of science.

Construction for the SNS started in September 2011, and total investment has reached 2.3 billion yuan ($364.4 million).
