强流低发射度光阴极微波电子枪的优化设计
-
摘要: 为了实现高增益FEL,对其关键部件光阴极微波电子枪进行了优化设计,还就发射度补偿技术进行了较详细的考虑,并用PARMELA程序进行了粒子动力学的模拟,初步给出了为了降低初始电子束团横向发射度的的优化参数。Abstract: To realize the requirement of SASE FEL to electron beam, this paper optimizes the design of photo-cathode RF gun and considers the emittance compensation techniques specifically. It also makes the simulation of the particle dynamics with PARMELA. At last it gives out the optimized parameters of the initialized electron beam to minimize the normalized transverse emittance.
