Study of medium beta elliptical cavities for CADS

Abstract

The China Accelerator-Driven Sub-critical System (CADS) is a high intensity proton facility to dispose of nuclear waste and generate electric power. CADS is based on a 1.5 GeV, 10 mA CW superconducting (SC) linac as a driver. The high energy section of the linac is composed of two families of SC elliptical cavities which are designed with geometrical beta 0.63 and 0.82. In this paper, the 650 MHz β=0.63 SC elliptical cavity is studied, including cavity optimization, multipacting, high order modes (HOMs) and generator RF power calculation.

“…In 2010, the ADS research project was started by the Chinese Academy of Sciences, and the project China initiative Accelerator Driven System (CiADS) was approved in 2015. Its goal is to build a megawatt grade ADS demonstration facility in Huizhou, Guangdong [10][11][12][13][14][15][16][17][18]. 90 Sr 137 Cs ADS consists of three sub-systems: proton accelerator, spallation target and sub-critical reactor [19][20][21][22].…”
