THE CONCEPTUAL DESIGN OF THE CHINA WHITE NEUTRON SOURCE

In order to feed the nuclear data needs for design of the Chinese Accelerator Driven sub-critical System (CADS) and new generation nuclear energy systems, we plan to construct the China White Neutron Source (CWNS). The CWNS will be composed of a Proton Linac, an Accumulator Ring, a Target and Experimental Facilities. The linac is designed to deliver a proton beam having an average current of 1 mA at energy up to 300 MeV. The revolution frequency of the accumulator ring will be ~1.4 MHz. Two spallation targets are planned, with one for short pulsed modes and the other for micro-pulsed mode.
