储存环光学速调管磁场分析

在合肥国家同步辐射实验室的储存环上，插入件光学速调管已安装完成，对光学速调管的磁场分布进行了一些附加测量，分析了横向磁场的空间谐波分量；测量了积分场的分布，对积分场变化的原因作了一定探讨。还测量了磁场横向分布的均匀度，为将要进行的相干辐射和自由电子激光研究提供实验数据；最后用实测的磁场对光学速调管自发辐射进行了数值模拟，结果表明这个光学速调管基本上满足实验要求。

The Analysis of the Magnetic Field of TOK in Storage Ring

An insert device TOK has been built up and mounted on the storage ring of NSRL.The magnetic field distribution of TOK is additionally measured,and the harmonic components of magnetic field distribution in strength were analysed.And the integral field distribution is measured, and the investigation of the origin of the integral field variation is taken.The uniformity of the transverse distribution of the field is checked to provide the experimental data for the coherent harmonic generation and FEL investigation in the future.Finally,numerical simulation of spontaneouse radiation from TOK is taken with the measured data,and the result illustrates that the TOK can satisfy the experimental requirement.
