Programmable Hard-X-Ray Spectral Comb Generation via Laser-Compton Scattering
Hao Zhang, Ji Qiang, 1Ji Qiang +2
Independent control of line spacing and offset underpins programmable frequency-comb spectroscopy, yet it has not been established for hard-X-ray sources based on inverse Compton s…
A compact accelerator for MHz high repetition rate soft x-ray free electron laser
Ji Qiang
High-brightness X-ray Free Electron Lasers (FELs) produce spatially and temporally coherent pulses on attosecond to femtosecond timescales, providing a transformative tool for disc…
Physics-Guided Inverse Design of Optical Waveforms for Nonlinear Electromagnetic Dynamics
Hao Zhang, Jack Hirschman, Randy Lemons +7
Structured optical waveforms are emerging as powerful control fields for the next generation of complex photonic and electromagnetic systems, where the temporal structure of light…
Upstream Laser-based Longitudinal Enhancement of Relativistic Photoelectrons
Hao Zhang, Randy Lemons, Jack Hirschman +23
Controlling the longitudinal phase space of high-brightness relativistic electron beams is crucial for advancing a broad spectrum of charged-particle-based instrumentation and scie…
Beam Halo Formation via Longitudinal-Transverse Coupling in Continuous-Wave Photoinjectors
Zhen Zhang, Yuantao Ding, David Cesar +3
Beam halo formation poses a critical challenge for high-repetition-rate continuous-wave (CW) free-electron lasers (FELs), directly affecting beam quality and machine protection, as…
