| 4 | The compensation of quadrupole errors and space charge effects by using trim quadrupoles显示文摘The China Spallation Neutron Source (CSNS) accelerators consist of an H- linac and a proton Rapid Cycling Synchrotron (RCS). RCS is designed to accumulate and accelerate proton beam from 80 MeV to 1.6 GeV with a repetition rate of 25 Hz. The main dipole and quadruple magnet will operate in AC mode. Due to the adoption of the resonant power supplies, saturation errors of magnetic field cannot be compensated by power supplies. These saturation errors will disturb the linear optics parameters, such as tunes, beta function and dispersion function. The strong space charge effects will cause emittance growth. The compensation of these effects by using trim quadruples is studied, and the corresponding results are presented. | AN YuWen WANG Sheng | 2011 | Science China(Physics,Mechanics & Astronomy)2011,54,S2: | 1 |

| 10 | Design and commissioning of a wideband RF system for CSNS-Ⅱ rapid-cycling synchrotron显示文摘The China Spallation Neutron Source(CSNS) upgrade project(CSNS-Ⅱ) aims to enhance the beam power from 100 to 500 kW. A dual-harmonic accelerating method has been adopted to alleviate the stronger space-charge effect in rapid-cycling synchrotrons owing to the increased beam intensity. To satisfy the requirements of dual-harmonic acceleration, a new radiofrequency(RF) system based on a magnetic alloy-loaded cavity is proposed. This paper presents design considerations and experimental results regarding the performance evaluation of the proposed RF system through high-power tests and beam commissioning. The test results demonstrate that the RF system satisfies the desired specifications and affords significant benefits for CSNS-Ⅱ. | Jian Wu Xiang Li Bin Wu Chun-Lin Zhang Yang Liu Wei Long Xiao Li | 2024 | Nuclear Science and Techniques2024,35,1: | 0 |
