Arbitrary manipulation of the temporal and spectral properties of x-ray pulses at free-electron lasers would revolutionize many experimental applications. At the Linac Coherent Light Source at Stanford National Accelerator Laboratory. the momentum phase-space of the free-electron laser driving electron bunch can be tuned to emit a pair of x-ray pulses with independently variable photo... https://www.getpureroutine.com/hot-sale-ethical-nutrients-mega-magnesium-powder-citrus-450g-for-sale-save-big/
