Abstract
The βg of cavity in superconducting linac will determine how many cavities and cavity-types will be used in a project, and then it will affect to the total costs. In this paper, to get the most suitable βg of cavity,a linear approximation model has been proposed and a code has been developed combined with the algorithm of the particle swarm optimization(PSO). Then it was been examined in the project of China Accelerator Driven sub-critical System(C-ADS). Finally it was passed and got a set of the most suitableβg and the corresponding physical design. The new design has certain advantages over the existing design for the number of cavity type has been reduced while the total number of cavities was not increased.
