ID30A-1 / MASSIF-1
MASSIF-1 is a world leading unique facility for the high throughput, fully automatic characterisation and data collection of macromolecular crystals. The new service is not designed to replace user visits to the synchrotron, but rather to do the hard work of screening crystals or collecting routine data sets through the night, freeing researchers to spend more time on challenging data collection problems and study the underlying biology.
The software routines used on MASSIF-1, the beamline itself and the RoboDiff sample changer have been described in the following publications:

MASSIF-1 has a highly intense beam (3 x 1012 ph/sec) with a size of 100 µm x 65 µm (H x V FWHM) at a fixed energy of 12.835 keV (0.966 Å). Apertures can be used to define a beam between 100 and 10 µm in diameter. The beamline is optimised for fully automatic data collection and sample evaluation with a new robotic system (RoboDiff) and high capacity dewar (240 spine pins). New automated services use mesh scans to fully evaluate crystals and centre the optimal volume to the beam, this position is then characterised and data collected, or not, depending on user request and parameters defined in the diffraction plan in ISPyB. No restrictions are placed on samples, loop size or crystal quality. As this is a fully automatic high throughput service samples must be registerd in the ISPyB data base with sample names and puck barcodes.

The beam is 100 µm x 65 µm (H x V FWHM) but apertures can tailor the beam down to 10 µm.
