While nuclear reactors such as the China Advanced Research Reactor in Beijing provide neutrons for researchers, the country lacks a spallation neutron source for materias testing. The China Spallation Neutron Source presently built near Beijing consists of a 200m-long 80MeV linac that accelerates protons which are fed into a 1.6GeV 238m-circumference synchrotron. The protons are fired into a solid tungsten target that can produce a 100kW beam of neutrons with 25 bunches of particles released every second. The facility has room for a total of 20 instruments.
