Productivity at a beamline depends as much or more on the control system the users interact with as it does inherent brilliance of the X-ray source or speed of the detector. Ease of defining the experiment, stability of the beam, quick and repeatable alignment of the sample, robust optimization of intensity on sample, ability to routinely handle 15x15x30μm crystals, routine movement from 7 KeV to 13.5 KeV, a user notes section, archiving the data automatically, all make for a highly productive trip to the beamline. The control system at SER-CAT has been redesigned with these ideals in mind, and both the philosophy and results of this work will be presented.
