Micro-X-ray absorption near edge structure spectroscopy investigations of baroque tin-amalgam mirrors at BESSY using a capillary focusing system

Capillary μFocus X-ray lenses with parabolic and elliptic profile

“…Poly-chromaticity of a capillary lens is the reason for its widespread use in spectroscopic measurements such as micro X-ray Absorption Spectroscopy (m-XAS) and micro X-ray Fluorescence Analysis (m-XRF). At the BESSY KMC-2 beamline a single-bounce elliptical mono-capillary is in use for m-XAS [8,9] and m-XRF measurements since 2004 [10]. Further improvements in these methods motivated our activity in the development of elliptically and parabolic-shaped capillary lenses.…”

Two-step hard X-ray focusing combining Fresnel zone plate and single-bounce ellipsoidal capillary

“…However, single-bounce capillaries proposed by Balaic et al (1995) show a great potential in developing nanofocusing techniques. Parabolic and elliptical capillaries have a large focal distance and very high reflectivity (Balaic et al, 1995;Huang & Bilderback, 2003; Bartoll et al, 2004;Bjeoumikhov et al, 2005;Pinakidou et al, 2006). In a typical process the predetermined capillary profile is achieved by 'pulling' an originally straight uniform glass tube with accurate control of mechanical movements and heating parameters.…”

Performances of synchrotron radiation microbeam focused by monolithic half focusing polycapillary X-ray lens

“…The fabrication of the capillary optics is simple, and besides, they can be expediently used in many fields [7][8][9][10][11]. There are some studies on the application of capillary optics in focusing the synchrotron radiation [3,[12][13][14][15][16][17][18][19].…”

“…Most of the studies are on a single capillary or an assembling polycapillary X-ray lens [12][13][14][15][16][17]. A MHFPXRL is used to focus the synchrotron radiation in Refs.…”
