China Spallation Neutron Source marks first anniv. of operation

Photo taken on July 24, 2019 shows the China Spallation Neutron Source (CSNS) at Dalang Town in Dongguan, south China's Guangdong Province. Friday marked CSNS's first anniversary of being put into operation after it passed the national acceptance test. The CSNS is the nation's first research facility providing the most intense pulsed neutron beams for scientific research. Spallation neutron source can accelerate protons before smashing them into a target to produce neutrons. The neutrons are then sent to numerous instruments that are used by researchers to study materials. The neutrons act as a "super microscope" to probe the structure of the microscopic world, similar to x-rays. (Xinhua/Liu Dawei)
