设计了一台52 MHz射频四极直线加速器，作为SSC直线加速器系统（分离扇区回旋加速器注入器）的初始结构。设计注入能量为3.5keV/u，输出能量为143 keV/u。用三维粒子模拟程序BEAMPATH研究了该装置中的束流动力学。模拟结果表明，该结构的特点是稳定值的束流传输效率（至少95%）的零电流模式和空间电荷占主导地位的制度。束流在该加速器中的横向和纵向质量都很好，很容易被漂移管直线加速器（DTL）接受。研究了叶片误差和空间电荷误差对束流参数的影响，确定了叶片加工和校准的工程公差。
A 52 MHz Radio Frequency Quadrupole (RFQ) linear accelerator (linac) is designed to serve as an initial structure for the SSC-Linac system (injector into Separated Sector Cyclotron). The designed injection and output energy are 3.5 keV/u and 143 keV/u, respectively. The beam dynamics in this RFQ have been studied using a three-dimensional Particle-In-Cell (PIC) code BEAMPATH. Simulation results show that this RFQ structure is characterized by stable values of beam transmission efficiency (at least 95%) for both zero-current mode and the space charge dominated regime. The beam accelerated in the RFQ has good quality in both transverse and longitudinal directions, and could easily be accepted by Drift Tube Linac (DTL). The effect of the vane error and that of the space charge on the beam parameters have been studied as well to define the engineering tolerance for RFQ vane machining and alignment.
