Abstract
Section titled āAbstractāIn the present paper we describe X-ray glitches and diffraction losses in monocrystalline diamond X-ray refractive lenses. For this purpose, X-ray spectroscopy of several types of diamond lenses was done at the BM31, ESRF. X-rays were propagating through lenses, while the transmitted intensity was measured at different energies. Use of compound refractive lenses, that were perfectly aligned by stacking in a single plate, gave us strong diffraction losses, reducing the outgoing signal by maximal value of 35%. The magnitude of the effect was then minimized down to ~ 10% by use of CRLs compiled from individual lenses with different crystallographic orientation. At the same time, X-ray glitches did not affect any focal spotās size or shape while only arousing the darkening of the focal spot at exact energies of X-ray glitches.
