摘　　要： 　介绍了正在研究设计的调谐强流电子束束心轨迹的计算机智能系统。根据目前正在设计建造的"神龙一号"加速器束流输运环境,为抑制束心螺旋运动,适应束输运磁场元件无散热装置,调谐过程中应尽量减少实验次数,智能调谐方法主要采用数值模拟和计算机克隆调谐和人工调谐相结合。以束心轨迹的数值模拟为基础,对束心位置调谐过程中的核心部分二极场调谐磁元件的调谐特性曲线进行了数值模拟,并与实验获得的调谐特性曲线进行了比较。获得了数值模拟和实验的初步结果。 An intelligent tuning system for the high current LIA is being designed at Laboratory of Accelerator Physics and Application, Institute of Fluid Physics. The goal to build the system is to adjust the beam centroid trajectory automatically for 'Dragon - I', which is a 20MeV, 2.5kA, 60ns pulsed electron LIA under construction. The simulation results show that to obtain pulsed electron beams with good quality and to reduce corkscrew amplitude, beam trajectory tuning is necessary. Three tuning methods adopted in the system are tuning manually, computer clone tuning and intelligent tuning. Both simulation and experiments have been performed to obtain the tuning curve of the first steering coil in the first cell. Details of the design, the tuning strategy and some of the tuning simulation and experimental results are presented in this paper.
