High-transformer-ratio plasma-based afterburner for extending X-ray free-electron laser photon energies to 50 keV
Songtang Han, Letian Liu, Zhiyan Yang +3
Bright coherent X-rays in the 50 keV range are highly desirable for applications in materials science, high-energy-density physics, and nuclear physics, but are difficult…

Generating 10 GW-class isolated zeptosecond x-ray bursts through bootstrapping two plasma-based accelerator stages
Qianyi Ma, Yuhui Xia, Zhenan Wang +8
A method is proposed to generate coherent, intense zeptosecond x-ray pulses by using the electron beam produced by a laser wakefield accelerator (LWFA) stage as the driver for a be…
