一种新的微型摇摆器

A NOVEL MICROWIGGLER

研究了一种新的微型摇摆器结构，给出了其场分布的二维解析公式。理论研究结果表明：该微型摇摆器的场分布具有很好的正弦特性，在３ｍｍ周期，其峰值磁感应强度可望达到５Ｔ。

AbstractA novel structure of the microwiggler is presented,seen in Fig.1.This paper developed asimplified theoretical model of the microwiggler.According to the model,an analystic formulaof the magnetic field in two dimensions is getted.A calculated program(PWMW一Ⅰ)is developedfrom the formula.PWMW一Ⅰcan calculated the field on the axis and the off一axis for the num-ber of periodes N,and the entrance or the exit of the microwiggler. Three model with different pe-riod(10mm, 5mm and 3mm )is designed on the program,seen in table一1.The 5T peak field forthe period of 3mm at the gap of 1mm is getted.Moreover,the method for the design of the entranee and exit of the microwiggler is sug-gested.Two examples is given in Fig.4 and Fig.5.
