Abstract
The China Spallation Neutron Source (CSNS) is designed to deliver a 1.6GeV proton beam to a solid metal target for neutron scattering research. It will be constructed in two phases. In the 1st phase, the beam power is designed to be 100kW. In the 2nd phase, the beam power will be upgraded to 500kW by doubling the linac output energy and beam current. The accelerator complex consists of a 50keV H⁻ ion source, a 3MeV Radio Frequency Quadrupole (RFQ), a 80MeV Drift tube Linac (DTL), and a 1.6GeV rapid-cycling synchrotron (RCS). Until March 2016, the front end and the first tank of DTL have been fully commissioned. The primary design goals of peak current, transverse emittance and beam energy have been achieved. This paper reports on the methods and the results of the commissioning.
