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。
At the storage ring of the National Synchrotron Radiation Laboratory in Hefei, the optical klystron of the insert has been installed and some additional measurements have been done on the magnetic field distribution of the optical klystron. The spatial harmonic components of the transverse magnetic field have been analyzed. The integration field The distribution of the field changes made a certain discussion. The uniformity of transverse distribution of the magnetic field was also measured to provide experimental data for the coherent radiation and the free electron laser to be carried out. Finally, the measured magnetic field was used to simulate the spontaneous emission of the optical klystron. The results show that the basic To meet the experimental requirements.
