Xijie Wang
Distinguished Scientist, SLAC National Accelerator Laboratory
BioXijie Wang is a distinguished scientist and the founding director of SLAC MeV-UED user facility at SLAC National Accelerator Laboratory. Xijie Wang has more than 30 years' experience in accelerator physics, free electron laser, THz, and ultrafast science and technology. Xijie pioneered the idea using mega-electron-volt electrons for ultrafast electron diffraction (MeV-UED) and ultrafast electron microscope (MeV-UEM). Under Wang’s direction, SLAC has become the world leader in ultrafast electron scattering technologies including single-shot, diffuse scattering, micro-diffraction, operando and in-situ, the first ever femto-second gas and liquid phase UED. These technologies have opened new frontiers in ultrafast science and materials in extreme conditions, produced insight into ultrafast structure dynamics of 2-D materials; control of the topological properties of matter; and atomic & molecular movies of complex materials such as perovskite and fundamental chemical processes in gas and liquid phases. He established the first ultrafast electron scattering user facility in the world – SLAC MeV-UED in 2019. Xijie Wang initiated superconducting RF gun R&D program at SLAC, and he led the effort established SRF gun R&D for LCLSII-HE.
Prior to his time at SLAC, Wang spent over 20 years at Brookhaven National Laboratory (BNL), where he led development and operations of the Accelerator Test Facility (ATF) and the Source Development Laboratory (SDL). Wang played a leading role in research on laser accelerators, high-brightness electron beams, X-ray free electron lasers (FEL), RF deflector for LCLS, THz and MeV-UED at BNL. He developed photocathode RF gun injectors that derived the first saturation of both high-gain harmonic generation (HGHG) FEL at BNL’s ATF and Self-amplified spontaneous emission (SASE) FEL at Argonne National Laboratory. Wang and his collaborators carried out a series of pioneering FEL experiments in early 2000s: 2nd to 4th harmonic HGHG, VISA (Visible to Infrared SASE Amplifier) SASE FEL and nonlinear harmonic generation characterization; super radiance FEL, detuning and tapering for FEL efficiency improvement.
Xijie Wang has co-authored over 300 publications, including 8 in Science, 4 in Nature, 8 in Science Advances, 18 in Nature family journals, and over 20 in PRL.
