HPL:High-efficiency, high-resolution multiple monochromatic imaging based on a multilayer mirror array for laser–plasma diagnostics of X-ray continuum emission. This methodology was capable of operating with a spatial resolution of approximately 3 μm. https://lnkd.in/gVPyk6mS

PRL: Experimental Demonstration of an Emittance-Preserving Beam Energy Dechirper Using a Hollow Channel Plasma. Experimental results demonstrate a reduction in energy spread by nearly 1 order of magnitude, while keeping a negligible emittance increase. https://lnkd.in/gDKt9_sA

PRL:Instantaneous and Retarded Interactions in Coherent Radiation. They propose an alternative theory for electromagnetic radiation by decomposing the interactions into an instantaneous part and retarded part. https://lnkd.in/g8_czhrV

HPL: Suppressing filamentation instability due to laser beam self-filtering. It is shown that self-filtering can significantly increase the permissible values of the B-integral, at which the beam quality remains acceptable. https://lnkd.in/gqv4DZFr

PR Research: Highly polarized energetic electrons via intense laser-irradiated tailored targets. The particle-in-cell simulations demonstrate the feasibility of highly polarized electrons with polarization of 60% and charge of 8 pC. https://lnkd.in/g3sgeFMj

Nat.Comms.: Cylindrical compression of thin wires by irradiation with a Joule-class short-pulse laser. Researchers show that a converging cylindrical shock is generated compressing the wire material to extreme conditions. https://lnkd.in/e4r9AkGR

HPL: Generation of polarized electron beams through self-injection in the interaction of a laser with a pre-polarized plasma. The evolution of the electron beam polarization is studied based on the Thomas–Bargmann–Michel–Telegdi equation. https://lnkd.in/gqg7V-uv

Nat.Photon.: All-optical nonlinear Compton scattering performed with a multi-petawatt laser. Researchers present an experiment in which a laser-accelerated GeV electron scatters off laser photons and converts them into a single gamma-ray photon. https://lnkd.in/ghS3TaPw

ELI:Researchers’ Night 2024 at ELI Beamlines attracted hundreds of visitors. The program included lectures, guided tours, and many hands-on activities both for adults and children. https://lnkd.in/g9hGi8y4

NIF: LLNL Presents on Fusion Energy at Industry Collaboration Event. LLNL recently joined representatives from higher education, government officials, and tech industry guests and moderators at the Roadrunner Technology Forum in Albuquerque, New Mexico. https://lnkd.in/g6FMMg9Y
