Shutter-Less Crystallography

A CMOS_8M detector is installed on the MBC beamline (4.2.2) at the Advanced Light Source in Berkeley. It operates in the shutter-less data acquisition mode. A complete crystal dataset takes just 3 minutes. The final data structures have higher resolution and are taken with less radiation damage than with conventional CCD systems.
