Microfocus Cu-K/sub /spl alpha// source for femtosecond X-ray science

摘要

We demostrate a sub-picosecond 1-kHz femtosecond X-ray source (flux: 5/spl times/10/sup 10/ photons/s) with a well accessible quasi-point size (10 /spl mu/m diameter) providing Cu K/sub /spl alpha// emission in continuous operation (10 hours), which we use to characterize two different types of focusing optics.
