The Diamond Light Source welcomed it first users in February last year at which time seven beamlines were functional. Now many more are on the way at this globally important research facility. Supplying the motion control for the project has been a challenge for Delta Tau, which reports that by the completion of phase two at the facility it will have installed approaching 1500 axes of motion for the project.

The light generated within the synchrotron ring is directed to beamlines and accelerated using bending magnets located at the insertion points around the storage ring. Once the light enters the beamline, it is guided, intensified or deintesified using series of slits, lenses and crystals; the angles and positions of which are dictated using electric motors whose motion commands are generated by Delta Tau controls. While most of the electric motors used are stepping types, there are also AC and brushed DC servo motors together with some piezo electric motors for fine adjustments. The same Delta Tau motion controllers handle all these mixed motor technologies.

Indeed, for the second phase installations, Delta Tau has a specially developed multiple axis control systems called the Geobrick LV, which has eight inherent servo drives capable of controlling any disparate type of motor – AC servo, DC servo or steppers. The compact new controller has a tiny footprint, slim profile and yet is packed with powerful electronics and fully functional PC. The Geobrick LV will enable simpler and quicker installation, while saving valuable space.
