ID30A-3 / MASSIF-3


Fixed energy microfocus beamline
Status:  open


  • Life Sciences


  • MASSIF-3 is a microfocus beamline (15 µm diameter), operating at fixed energy (12.81 keV). The beamline is dedicated to protein crystals of small size, inhomogeneous protein crystals, and fast data collection, and is also suitable for SAD measurements (Se, Pt, Au,...). MASSIF-3 is equipped with a MD2 micro-diffractometer and with a FlexHCD sample changer for SPINE pucks and UniPucks. Diffraction data are recorded on a Eiger X 4M detector that allows data collection at a very high frame rate (up to 750 Hz).
