In article number 2000326, Junho Shin, Young Uk Jeong, Jungwon Kim, and co‐workers developed a timing system with sub‐10‐fs stability for MeV‐class ultrafast electron diffraction apparatus. An array of methodologies, including radiofrequency‐to‐laser synchronization, optical timing monitoring and electron dispersion control, is applied to enable THz‐streaking with few‐femtosecond resolution. With the THz‐driven streak camera, timing of ultrafast electron bunch is stabilized to 5.5 fs in rms.

超快光学器件：采用THz驱动条纹相机的超快电子衍射时间低于10-fs（Laser Photonics Rev. 15（2）/ 2021）

在编号2000326的文章中，Junho Shin，Young Uk Jeong，Jungwon Kim和他的同事开发了一种MeV级超快电子衍射仪具有低于10fs稳定性的计时系统。应用了一系列方法，包括射频到激光同步，光学定时监控和电子色散控制，以实现具有飞秒分辨率的太赫兹条纹。借助太赫兹驱动的条纹相机，超快电子束的定时稳定在rms的5.5 fs。
