| 摘 要： | 在交汇段设计理论的基础上，针对北京大学ERL的具体情况，对交汇段的束流传输结构进行了优化设计，通过模拟得到了满足要求的一组设计参数；研究了空间电荷效应以及相干同步辐射对束流发射度、能散及包络的影响。结果表明：空间电荷效应对发射度影响不大，但对束流包络影响较明显；相干同步辐射引起的发射度增长及能散较小，且不影响束流包络。

| Abstract: | Based on the merger design theory, the transportation of the merger in PKU-ERL is designed,and the optimized parameters is given which can satisfy the demands of PKU-ERL. The increasements of the emittance and energy spread caused by space charge and coherent synchrotron radiation(CSR) in the merger part are studied. Simulation results show that space charge influences the beam envelope obviously but has little influences on the emittance. CSR has little influence on the emittance, the energy spread and the envelope. |
