Neutron moderation and neutron transport in target-moderator-reflector(TMR) system of China spallation neutron source(CSNS) were simulated by using MCNP code.Neutron energy spectra and angular distributions were calculated using different sets of parameters.The results show that placing the poison in the center of decoupled poisoned hydrogen moderator(DPHM) with a deviation of 5 mm to the downstream window can optimize the design.
