The Ag-IµS HB is the ideal X-ray source for high-pressure crystallography, either for single crystals or for powder samples. The advantages of the Ag-IµS HB for high-pressure research are the reduced absorption and the „compression" of the reciprocal space. Furthermore, the focused beam leads to a reduction of the background that is caused by scattering from the gasket. It either delivers a focused beam with a FWHM of 95 µm and a divergence of 5 mrad suitable for diffraction on single crystals, or a beam with a FWHM of about 155 µm and a divergence of 2.5 mrad suitable for diffraction experiments on smaller amounts of powder samples (e.g. in a diamond anvil cell).
