21. 3D atomic structure determination with MeV electron diffraction

Alke Meents

8/27/25, 10:00 AM

For UED experiments DESY operates the ‘relativistic gun for atomic exploration (REGAE)’. REGAE generates electron pulses with an energy of 2 - 5 MeV and a charge of up to 100 fC. An additional buncher cavity allows compress these pulses to 20 fs. For diffraction experiments with solid state samples, REGAE is equipped with a crystallography goniometer and a Jungfrau 1M detector, which allowed...

22. The Future RUEDI (The Relativistic Ultrafast Electron Diffraction and Imaging) UK facility

27. MeV UED facility at SJTU

Dao Xiang (SJTU)

8/27/25, 11:00 AM

Abstract: The National Science Foundation of China supported the construction of a MeV UED/UEM facility at Shanghai Jiao Tong University from 2014 to 2019. The facility achieved a high temporal resolution of <50 fs (FWHM) and supported about 20 experiments since 2020. I will discuss the critical technologies that enabled the high temporal resolution.

28. KAERI MeV-UED: Setup and Applications to Ultrafast Chemical Dynamics

Jun Heo (KAERI)

8/27/25, 11:30 AM

The MeV-UED facility at the Korea Atomic Energy Research Institute (KAERI) has been
constructed to investigate ultrafast structural dynamics with a focus on experimental flexibility.
This talk will provide an overview of the beamline configuration and timing system, followed
by a detailed look at the experimental setup, including gas sample delivery system, interaction
chambers, and...
