Jitter-free Ultrafast Electron Diffraction Technology

We introduce on ultrafast electron diffraction (UED) technology that observes the movement of fast-moving atoms. Recently the Korea Atomic Energy Research Institute has built the fastest electron diffraction facility in the world with the achievements of increasing beam brightness and improving temporal accuracy with jitter-free technology. We introduce the unique characteristics of the device with 90-degree-bending structure and conclude with the current status and prospects of the UED and its applications.
