摘要:

杰斐逊实验室红外自由电子激光器的升级正在建设中。它将在2-10微米的波长范围内提供10千瓦的输出光功率。自由电子激光器将由一个中等大小的80-210 MeV,10 mA的能量回收超导RF(SRF)直线加速器驱动。摇摆器、低束能量和高束电流的严格相空间要求使设计受到许多约束。这些都是由于横向和纵向相空间管理的需要,集体现象(空间电荷,尾流场,束分裂(BBU)和相干同步辐射(CSR))的潜在影响,以及自由电子激光和加速器RF系统之间的相互作用。本报告解决了这些问题,并提出了一个加速器的设计解决方案,满足物理现象和操作的必要性所提出的要求。

英文摘要:

An upgrade of the Jefferson Lab IR FEL is now under construction. It will provide 10 kW output light power in a wavelength range of 2-10 microns. The FEL will be driven by a modest-sized 80-210 MeV, 10 mA energy-recovering superconducting RF (SRF) linac. Stringent phase space requirements at the wiggler, low beam energy, and high beam current subject the design to numerous constraints. These are imposed by the need for both transverse and longitudinal phase space management, the potential impact of collective phenomena (space charge, wakefields, beam break-up (BBU), and coherent synchrotron radiation (CSR)), and interactions between the FEL and the accelerator RF system. This report addresses these issues and presents an accelerator design solution meeting the requirements imposed by physical phenomena and operational necessities.
