K6.6 - Station for high-precision X-ray optics (HPXO)

The station is dedicated for research in the field of solid-state physics, materials science, bio- and nanotechnology, for high-precision structural diagnostics of the organic and inorganic condensed matter.

Methods: high-precision X-ray diffraction, diffraction topography, high-precision X-ray reflectometry, phase analysis, X-ray standing wave method, multiwave diffraction, etc.

Samples: almost perfect crystals, surface layers, thin films and boundaries, organic and inorganic multi-layer structures, semi-conductor superlattices and nanostructures, structures with quantum wells, threads and dots, nanostructures on porous layers, real structure of crystals and crystal defects.

The station equipped with:

• vacuum double crystal monochromator (Energy range E = 2...40 keV);
• multicircle goniometer, realizing X-ray optical schemes for a great number of methods;
• gamma spectroscopy complex with semi-conductor germanium detector for the X-ray standing waves method and X-ray fluorescent analysis;
• the kinematic scheme of the station includes 30 steppers, 8 electromagnets and 2 piezoactuators, controlled through the high-speed communication channels.

Stabilizing systems of the spatial position of the SR beam (accuracy ~ 10 µm) and the angular position of the second monochromator crystal (accuracy ~ 0.03 second of arc) provide necessary conditions for carrying out precision X-ray diffractional experiments.

The station automatization system provides remote control of all units and mechanisms through the high-speed communication channels and flexible control of one-, two- and three-dimentional measurments.
