  The China Spallation Neutron Source (CSNS) linac consists of a 50 keV H− ion source, a 3 MeV RFQ, and an 80 MeV alvarez type DTL. It provides an H− beam of 15 mA peak current with a pulsed beam width about 420 μs and a repetition rate of 25 Hz for injection into the following 1.6 GeV rapid-cycling synchrotron (RCS). The transverse and longitudinal beam optics is introduced. The original design scheme is optimized based on the end-to-end simulation. Besides beam dynamics, the commissioning plan for linac is also presented, including the commissioning correlated parameters, beam instrumentation used in commissioning, the goal at different commissioning stages.
