High field laser physics will extend from … WebThe early success of the Linac Coherent Light Source (LCLS) has bolstered plans for more accelerator-based x-ray free-electron lasers (XFELs) in Europe and Asia. But the new machines create a challenge: The ultrabright femtosecond pulses generated by XFELs have properties far beyond previous sources. They carry a million times more pulse energy …
Web24 de jan. de 2024 · The laser field would then shake the particles, causing them to emit electromagnetic waves—in this case, gamma rays. The gamma rays would, in turn, generate new electron-positron pairs, and so on, resulting in an avalanche of particles and radiation that could be detected. "This will be completely new physics," Sergeev says. Web11 de abr. de 2024 · Bonding characteristics of the β-(Al x Ga 1−x) 2 O 3 alloy have been assessed from red luminescence and x-ray absorption near edge spectroscopy (XANES). Red luminescence, known as R1 and R2 lines, originates from crystal field split d-levels of unintentionally present Cr 3+ ions in the β-(Al x Ga 1−x) 2 O 3 alloy, is found to blueshift …
