为了使感生放射性降低到可以接受的水平,强流质子加速器必须减少束流损失.不同加速段间的束流匹配是减少束流损失和发射度增长的关键之一.研究了一台常温加速结构不同段间的束流传输线的匹配设计问题.采用TRACE3-D软件以及其他多粒子模拟软件,研究了在不同匹配状态下的束流特性.结果表明,设计所采用的横向和纵向匹配手段,能够有效地控制束晕产生和束流发射度的增长.

A high current proton accelerator requires very low beam losses in order to minimize the induced radioactivity to an acceptable level. Beam matching between the different accelerator sections is one of the key points to reduce the beam losses and emittance growth. A matching design study has been performed for the beam lines between the different types of normalconducting accelerating structures. In this paper, we will present the beamline design by TRACE3D code and multiparticle simulations of the beam behavior in different matching conditions. The results show that the beam halo and emittance growth have been well controlled with the matched design of the beam lines in both transversal and longitudinal directions.
