Sub-millimeter synchrotron X-ray focusing by crystal bender

Yoneda, Yasuhiro; Matsumoto, Norimasa; Furukawa, Yukito*; Ishikawa, Tetsuya*

Physica Scripta, T115, p.995 - 997, 2005/00

Sagittal focusing is known as one of the most efficient focusing methods for synchrotron X-rays which increases the photon density at the sample position. Results are reported on the performance of a fixed height exit bender with an unribbed silicon (311) crystal. The fixed height exit was achieved by using a 4-point bending mechanism. This bending mechanism is designed for the SPring-8 standard double crystal monochromator (DCM) of bending-magnet beamlines and the bender is installed as a second crystal of the DCM. By using unribbed crystal, the focusing beam size was kept 0.5 mm in the energy ranges from 35 - 60 keV. Since mirrors for high-energy X-rays are still under development at the moment, focusing techniques by crystal bender are demanded for many practical applications.

The main components of a new beamline for surface and interface crystal structure determination at SPring-8 are briefly described. Stages for the beamline monochromator are modified for making an incident X-ray intensity more stable for surface X-ray experiments. Absolute photon flux densities were measured with an incident photon energy. A new ultrahigh vacuum system is introduced with preliminary X-ray measurements from an ordered oxygen on Pt(111) surface.

Two-dimensional X-ray focusing by crystal bender and mirrors

Yoneda, Yasuhiro; Matsumoto, Norimasa; Furukawa, Yukito*; Ishikawa, Tetsuya*

AIP Conference Proceedings 705 (CD-ROM), 4 Pages, 2003/00

Results are reported on the performance of a fixed height exit bender with an unribbed silicon (311) crystal. The anticlasic crveture can be minimized for a recutangular Si (311) focusing crystal with "clamped" or "builtin" boundary conditions if the length to width ratio of the crystal is 1.42. The test crystal used in this study was manufactured from a 98mm$$times$$90mm$$times$$2mm dimension of float zone silicon. After final etching, the ratio of the crystal is 1.435. The sub-millimeter sagittal focusing was achieved by using a 4-point bending mechanism in energy ranges from 30keV to 60keV.
