BASEMA beamline is located on the bending magnet D09 port at SESAME. Most of the optics elements are retrieved from the ROBL beamline at ESRF due to the upgrade process. The components are adapted to meet the requirements of SESAME users. Within the beamlines optics hutch, the white light is collimated by a mirror, converted to a monochromatic beam by a double-crystal monochromator [Si(111) or Si(311)] running either in channel-cut or fixed-exit mode, and then vertically focused by a second mirror (See Figure). Besides collimating and focusing the beam, the two mirrors are used to reject higher harmonics. Depending on energy range, either the Si-coated (5-13 keV) or the Pt-coated surfaces (13-30 keV) of the two mirrors are used. The integrated flux at 400 mA and is higher than 1011 photons/s for most of the covered energy range (5 to 20 keV). The beam size on the sample can vary hundreds of micrometers to few millimeters. Using a sagitally-focusing second crystal in the monochromator, and the vertically focusing mirror, a spot-size of 0.4 x 0.4 mm2 can be achieved. This allows measuring small samples, often a necessity for very important and valuable small samples in archaeology and cultural heritage. With the energy range covered by the monochromator and the other optical components, including Be windows, the K-edges of elements Cr to Sn and the L-edges of elements Cs to Cm can be investigated (5-30 keV).
