Abstract

Abstract

The collimator at the end of the ring to target beam transport (RTBT) line is one of the key devices in the Chinese Spallation Neutron Source (CSNS) project. Design reliability of the collimator is extremely important since the high radiation on it due to its closeness to the target station. According to the working principle of the collimator and CSNS physical design requirements, comparing the design experience of similar foreign accelerator, the collimator is designed. Considering strict requirements of thermal deposition, power loss and material performance in the design process, the specific scheme is expounded. Using the result compared between Bethe-Bloch formula and SRIM software to determine the reliability of the simulation tool and simulation methods. According to the result of ANSYS finite element software simulation, the reliability of the collimator structure design is verified.
