The China Spallation Neutron Source (CSNS), operated by the Institute of High Energy Physics (IHEP), has been built at Dongguan city in China.

CSNS mainly consists of an H-linac, a proton rapid cycling synchrotron, a target station and three spectrometers. It is designed to accelerate proton beam pulses to 1.6 GeV energy at 25 Hz repetition rate, striking a solid metal target to produce spallation neutrons. The accelerator is designed to deliver a beam power of 100 kW with the upgrade capability to 500 kW by raising the linac output energy and increasing the beam intensity.
