Abstract:
The focusing properties and radiation resistance of refractive polymer X-ray lenses have been experimentally studied on an ESRF synchrotron. The axisymmetric X-ray lenses with parabolic profile have been manufactured by “imprinting” a high-precision stamp into a photocurable polymer. Results of measurements of the characteristics of lenses for 9.9-keV X-rays with an intensity of 10$^{13}$ ph/(mm$^2$ s) are presented and discussed.
