X-ray optical designs for the Linac-based Ultrafast X-ray source (LUX)

摘要

The Linac-based Ultrafast X-ray source (LUX) is a proposed recirculating linear accelerator for the purpose of producing intense, tunable, high repetition rate ultrafast x-ray pulses. An angle-time or position-time correlation is induced in the electron bunches by a dipole-mode RF cavity. Undulators and wigglers are sources of synchrotron radiation. Asymmetrically-cut crystals are used as optical elements of an x-ray pulse compression scheme. X-ray pulse durations of 50-100 fs are obtained over a range of photon energies from 2 to 12 keV. An undulator beamline consists of a collimating mirror, two asymmetric crystals and Kirkpatrick-Baez mirrors and provides compressed, monochromatic and focused x-rays for time-resolved experiments.
