European Synchrotron Radiation Facility
Grenoble, France
SC3 Automounter

The MASSIF (Massively Automated Sample Selection Integrated Facility) suite of beam lines comprises three individual end-stations, MASSIF-1, MASSIF-2 and MASSIF-3, all located at the first branch of ID30. All three beam lines run at a fixed photon energy slightly above the selenium absorption edge.

The third endstation MASSIF-3, in user operation since December 2014, offers a small X-ray beam (15 μm diameter) at a fixed energy (12.8 keV), and is dedicated to perform experiments with very small protein crystals. MASSIF-3 is equipped with a Eiger X 4M and a mini-diffractomer and a SC3 sample changer.

The optical design of MASSIF-3 makes use of a horizontally diffraction Si (111) monochromator, and compound refractive lenses (CRLs) and a half-Kirkpatrick-Baez (KB) geometry as the vertical and horizontal focusing systems, respectively. The X-ray sources for the three stations are canted undulators mounted on a special carriage on the storage ring. The MASSIF-3 undulator is a U21.2. It is a pseudo-monochromatic source with a single first harmonic at 12.9 keV. An overview of the setup of the optical and experimental hutches can be found here. 1
