摘要
提出小波函数反馈控制法 ,分别实现了在四种不同的初始质子分布情形下对强流质子束的束晕 混沌的有效控制 .控制后束晕强度因子变为零 ,束均方根半径、束横向动量平方和的平均值和相对平均发射度比控制前都减少至 1/2— 1/3.结果表明该方法十分有效 。
The wavelet function feedback method is proposed for controlling beam halo-chaos for high intensity proton beam in a periodic-focusing channel. After control for four different primary proton distributions,the halo intensity factor become zero,other statistical physical quantities (such as r(rms) and P-av(2)) and relative average emittances are more than doubly reduced. Simulation results show that the method is very effective and has its prospect for application.
