WebAn ultra-short ultra-intense laser can excite high-amplitude electron plasma waves or so called laser wakefields when it propagates in under-dense gas plasma. A laser wakefield accelerator makes use of such waves to accelerate charged particles (especially electrons and positrons). These plasma waves can sustain longitudinal acceleration fields over … WebApr 14, 2024 · A 3D laser scanner is used to obtain the 3D point cloud data of pebble, granite, and basalt, and the solid models of the three coarse aggregates are reconstructed. ... to the overall data.
