我们为NSC KIPT设计了一台100 MeV/100kW电子直线加速器，用于在亚临界组装的基础上驱动中子源。进行了束流动力学研究，以达到设计要求(对于99%的粒子，E=100 MeV，P=100 kW，E/E<；1%)。在本文中，我们将介绍设计过程和动态仿真结果。对于高强度长束脉冲直线加速器，BBU效应是一个很大的问题，在加速结构设计中特别注意。为了满足直线加速器出口的能量扩散要求，应在较低能量阶段剔除与同步粒子能量差较大的粒子，以便于准直系统的设计和辐射屏蔽。在第一个加速段的下游引入了一个带有4个弯曲磁铁的无分散弯曲轴；不需要的粒子将在那里准直。
We designed a 100 MeV/100 kW electron linear accelerator for NSC KIPT, which will be used to drive a neutron source on the basis of subcritical assembly. Beam dynamics studies have been conducted to reach the design requirements (E = 100 MeV, P = 100 kW, dE/E < 1% for 99% particles). In this paper, we will present the progress of the design and the dynamic simulation results. For high intensity and long beam pulse linear accelerators, the BBU effect is one big issue; special care has been taken in the accelerating structure design. To satisfy the energy spread requirement at the linac exit, the particles with large energy difference from the synchronous particle should be eliminated at a low energy stage to ease the design of the collimation system and radiation shielding. A dispersion free chicane with 4 bending magnets is introduced downstream of the 1st accelerating section; the unwanted particles will be collimated there.
