“…The ground powders were mixed with a binder and packed into the sample holder. The diffraction experiment was performed on the Aachen/Frankfurt (Darmstadt)/Tiibingen powder diffractometer (Arnold et al, 1989) with synchrotron radiation of ~ = 1.2122A from an Si(511) monochromator at beamline B2 of HASYLAB at DESY, Hamburg, Germany. The furnace was described by Arnold (1991).…”

The cubic-tetragonal phase transition at 571 K of the aluminate sodalite Sr8[AI12024](MoO4)2 (SAM) has been studied by following the position of the (pseudo-)cubic {400} reflections as a function of temperature. The high resolution of the synchrotron powder diffraction experiment allowed the temperature dependencies to be followed with good precision. The tetragonal a lattice parameter appears to be a linear extrapolation of the cubic one, with only a small upward shift at the transition, whereas the c parameter decreases strongly below 571 K. These observations can be explained by a model which assumes the superposition of a ferroelastic strain component, and a volume strain component. The volume strain can be rationalized as being the result of a 'shearing' of the sodalite framework. Causes and consequences of the 'shearing' in relation to the sodalite framework are discussed.

“…Therefore, the instrumental resolution of the new setup at P02.1 (PETRA III) is related to the extensively used in situ setup at B2 (DORIS III). Detailed information about this beamline is available in the literature (Arnold et al, 1989;Pennartz et al, 1992;Lö chner et al, 1993;. Typically a wavelength of about 0.7 Å was set at B2, close to the maximum flux at this beamline.…”

Advances inin situpowder diffraction of battery materials: a case study of the new beamline P02.1 at DESY, Hamburg

A brief review of in situ powder diffraction methods for battery materials is given. Furthermore, it is demonstrated that the new beamline P02.1 at the synchrotron source PETRA III (DESY, Hamburg), equipped with a new electrochemical test cell design and a fast two‐dimensional area detector, enables outstanding conditions for in situ diffraction studies on battery materials with complex crystal structures. For instance, the time necessary to measure a pattern can be reduced to the region of milliseconds accompanied by an excellent pattern quality. It is shown that even at medium detector distances the instrumental resolution is suitable for crystallite size refinements. Additional crucial issues like contributions to the background and available q range are determined.

“…• For precise phases identification of as-quenched Al-17Ni and Al-17Ni-2Sr samples high-resolution XRD measurements were performed at B2 [17] (bending magnet beamline) at room temperature. The samples measured in transmission mode were illuminated by well collimated and monochromatic photon beam of energy E = 26.11 keV (λ = 0.4748Å).…”
