  The successful mechatronics development i.e. modelling, simulation, design, build and test of a magnetic levitation stage at the Diamond Light Source is presented. The concept was to use a low control Bandwidth across the 6 degree of freedom MIMO system, to provide both an alignment stage and vibration isolation. The project simultaneously upskilled staff and developed a proof-of-concept system demonstrator at a low cost. The final motion stage was constructed for a component cost of less than £15,000.

  The decision was made to build a new Optics Metrology Lab at the Diamond Light Source in a location with 100 times higher floor velocity in the range 50-150Hz than the original location. This paper describes the successful engineering developments to mitigate this. The raft of measures included ‘skyhook¿ damping i.e. active damping using geophone velocity feedback, novel 2 stage passive vibration isolation and fundamental research into acoustic coupling of air conditioning noise. The new systems have been installed, the final performance tested and the optics scientists have been able to continue their sensitive measurements.
