The performance of the Monolithic Polycapillary X-ray Lens (MPXRL) for application in the Extended X-ray Absorption Fine Structure (EXAFS) technique is reported
especially
the main characters of the MPXRL such as gain in flux density
stabilizing effect
and high energy filtering. Experimental results show that the spatial resolution of the EXAFS facility based on the MPXRL is about 25 μm
and the gain in flux density of the Monolithic Polycapillary Focusing X-ray Lens (MPFXRL) is about 3 000 when the MPFXRL is used to focus the laser plasma pulsed X-ray for ultrafast time-resolved EXAFS experiments. These indicate that the MPXRL is helpful in the improvement of the EXAFS facilities.
