The "super microscope" to explore the microstructure of materials - the second phase of the China Spallation Neutron Source project started construction in Dongguan, Guangdong on March 30. Since the first phase of the project completed national acceptance and was put into operation in 2018, there have been more than 6,000 registered users. He has completed more than 1,500 projects and achieved a number of scientific and technological innovation achievements in key areas such as key aerospace components, lithium-ion batteries, rare earth magnetism, and new high-temperature superconductors.

The construction period of the second phase of the project is expected to be 5 years and 9 months. The number of neutron spectrometers will be increased to 20. The design index of the accelerator target beam power will be increased from 100 kilowatts to 500 kilowatts. This will not only effectively shorten the experimental time, but also Make experiments with higher resolution, measure smaller samples, and capture faster motion processes.
