Resumo
A high pressure CuBe cell with B4C anvil has being developed since 2004 for small- and wide-angle synchrotron x-ray scattering experiments under hydrostatic pressure up to 2GPa, at room temperatures. Recently, an optimized version of this cell was used to measure the pressure e ect on structure of Cardanol-Furfural-PAni Green Blend in SAXS beam line at Laboratorio Nacional de Luz Sincrotron- LNLS- Campinas . This cell has also been applied to investigate solid samples behaviour under external hydrostatic pressure since 2007 at LNLS. Moreover, it might also be used to investigate biological system as lipid-water dispersions without changes in its design. Magnetic eld up to 1.6 kGauss can be applied together the hydrostatic pressure in this cell, taken into account there is no magnetic signal from de CuBe, B4C anvil, and CuBe gasket used. Investigations about ReO2 behaviour under hydrostatic pressure up to 1.6 GPa were performed at LNLS-XPD and XAFS Synchrotron beam line, and the results revealed to be the ReO2 a good inner gauge pressure for 8keV-13keV energy range. This project has been developed by LNLS, UFES, IPEN/CNEN and IEA/CTA collaboration.
