【摘要】 通过采用各向异性聚焦及电四极透镜技术,设计出物理弥散达到0.38ps,边缘空间分辨力达到56lp/mm的新型条纹变像管。研制出对条纹相机高压输出、环境监测、扫描档位切换和相机工作方式选择的模块化程控系统。利用Nd:YLF(脉冲宽度8ps、波长263nm)脉冲激光器对相机的性能指标进行了标定,测得静态和动态空间分辨力分别为35lp/mm和25lp/mm,动态范围达到950∶1,时间分辨力达到8ps,在扫描和狭缝方向可实现独立变倍和KB显微镜耦合,便于对目标的空间分辨力进行灵活配置。更多还原

【Abstract】 Anisotropic focus electrodes and electric quadrupole lenses have been used to make a novel streak tube,whose physical temporal dispersion and edge spatial resolution are 0.38 ps and 56 lp/mm respectively.A modular remote-controllable system has been designed to control high voltage supply,environmental monitoring,deflection voltage switch and camera work mode.The Nd:YLF 8 ps pulsed laser was used to calibrate the performance index of the streak camera.The streak static and dynamic spatial resolution are 35 lp/mm and 25 lp/mm respectively.The dynamic range more than 950∶1 and time resolution of 8 ps are reached.Furthermore,the magnifications in slit and scanning direction can be adjusted respectively.When the camera is coupled with KB microscope,it is convenient to select amplification needed.更多还原
