Abstract
Two-dimensional imaging of an undulator x-ray source at different phot on energies has been observed by means of phase circular Bragg-Fresnel lens (BFL) at the ESRF ID6 beamline. The optical properties of the BF L in the energy range 6-18 keV have been studied. Imaging has been stu died on various orders of diffraction and on various harmonics of the undulator spectrum. Good resistance to a heatload of 100 W and 12 W/mm 2 in the white beam has been demonstrated.
