The PAINEIRA Group is responsible for the management and operation of the PAINEIRA beamline of the synchrotron light source Sirius, at the Brazilian Synchrotron Light Laboratory (LNLS).

The PAINEIRA beamline is designed for the techniques of X-ray powder diffraction for the characterization of polycrystalline materials such as ceramics, pharmaceuticals, minerals, oil, gas etc. In the PAINEIRA beamline it will be possible, for example, to study the formation of new crystallographic phases during chemical reactions.

Paineira Beamline

PAINEIRA (Powder X-ray Diffraction) will be a beamline optimized for the X-ray diffraction of polycrystalline materials in Debye-Scherrer geometry (capillary geometry or transmission mode). The beamline is aimed primarily at the structural characterization of materials in the powder form, such as ceramics, pharmaceuticals, minerals, catalysts, amongst others. The beamline will operate in high-throughput mode to rapidly characterize numerous samples. In addition, PAINEIRA will offer reaction cells and accessories for conducting experiments under in situ conditions as well as perform operando studies on functional materials and devices for energy storage and catalysis, for example.
