摘要
介绍了在自由电子激光研究中获得高亮度电子束的研究过程。电子束能量6.5 MeV,微脉冲束流强度大于4 A,微脉冲束流宽度25～28 ps,电子束能散小于1%,发射度小于20π mm·mrad。进行了出光实验,测量到受激辐射信号,受激辐射中心波长115 μm,谱宽1％。
Abstract
The main parts and experimental results of free electron laser (FEL) are introduced. The electron energy is about 6.5 MeV, the micropulse beam current is 4 A, the width is about 25 ps, the energy spread is 1%, the beam emittance is about 20π mm·mrad. First lasing of the far infrared FEL (FIR-FEL) at center wavelength of 115 μm is observed, the spectral width is 1%.
