Abstract Laser-driven compact particle accelerators can provide ultrashort pulses of broadband X-rays. well suited for undertaking X-ray absorption spectroscopy measurements on a femtosecond timescale. Here the Extended X-ray Absorption Fine Structure (EXAFS) features of the K-edge of a copper sample have been observed over a 250 eV window in a single shot using a laser wakefield acce... https://parisnaturalfoodes.shop/product-category/dulse-leaves/
