A new mini-beam device for protein crystallography

A fully motorized mini-beam device has been constructed for use in protein crystallography. This device separates the beam-defining aperture from the guard aperture into two distinct components, removing the need for pitch and yaw adjustments. Each aperture can be scanned separately using only x and y translations, allowing independent positioning of the beam-defining and guard apertures. Switching from mini-beam to the existing slit system is controlled by a single mouse click.
