Abstract：
The resonant frequency of the ferrite-loaded cavities used in the future China Spallation Neutron Source (CSNS) sweeps from 1.02MHz to 2.42~MHz. The ferrite property is very important to the accelerator structure in the CSNS ring. A primary experiment was set up to measure the μ_rQf value and the power density of different ferrite materials. According to the comparison results, 4M2 ferrite rings were chosen to meet the requirement of CSNS.
