用于未来短波长高亮度加速器驱动光源的光注入器需要产生具有超低发射度的电子束。在BNL的DUVFEL装置上，我们研究了纵向成形光阴极激光脉冲对电子束动力学的影响。我们报告的测量的纵向相空间分布和时间分辨的横向光束参数的高斯和平顶的时间激光脉冲轮廓。
The photoinjectors for future short wavelength high brightness accelerator driven light sources need to produce an electron beam with ultra-low emittance. At the DUVFEL facility at BNL, we studied the effect of longitudinally shaping the photocathode laser pulses on the electron beam dynamics. We report on measurements of the longitudinal phase space distributions and the time-resolved transverse beam parameters for both a Gaussian and a flat-top temporal laser pulse profile.
