ID30A-3 / MASSIF-3


Fixed energy microfocus beamline
Status:  open


  • Life Sciences


  • MASSIF3 is a microfocus beamline (15 ┬Ám 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 Mini-Diffractometer (MD2) and with a EMBL/ESRF Sample Changer (SC3). Diffraction data are recorded on a Pilatus3 2M detector (to be replaced by an Eiger 4M in January 2016) that allows data collection at a very high frame rate (>200Hz).
