BEAMLINE GUIDE
MANACA – MX at Sirius Synchrotron Source

Brazilian Synchrotron Light Laboratory
Sao Paulo, Brazil.
Brazilian Synchrotron Light Laboratory – LNLS
Brazilian Center for Research in Energy and Materials – CNPEM

MANACA (macromolecular, micro and Nano Serial Crystallography) will be the first macromolecular crystallography beamline at Sirius, optimized for high flux, micro-beam size and small beam divergence (0.3 mrad). The focus is optimized to 10 x 7 um (HxV) at sample position, but the beam size can be adjusted from 100 x 80 um to 10 x 7 um allowing match the beam to the crystal size. Additionally, the beam can also be cut to achieve smaller sizes (e.g. 5×5 um). The photon flux at sample will be ~3x1012ph/s/100mA at 12.5 keV and energy range from 6 to 20 keV. Setups for serial crystallography data collection and analyses, as well as automation procedures, are being prepared.

The great beam characteristics provided by Sirius and the high stability and precision of the optics and experimental station will allow the diffraction of challenging samples such as viruses (and other big unit cell crystals), membrane proteins and complexes, which commonly yield small crystals. The energy range and beamline setup will allow native SAD phasing, eliminating the necessity of additional experiments to solve new structures. The experiment control will be done using a user-friendly graphical interface (MXCuBE), and automatic data processing (from data reduction to initial modeling) will be available.1
