UKRI-1417 Mirror Mount Motorized Actuators And Controller(s)

The Science and Technology Facilities Council (STFC, part of UK Research and Innovation (UKRI)) has a requirement for the supply of motorised actuators and accompanying controller(s), to be incorporated as part of the Extreme Photonics Applications Centre (EPAC) Project. The motorised actuators and controller(s) will form part of a Beam Steering System for a large laser facility. In the facility, multiple laser beams propagate hundreds of metres; the position of the beams can fluctuate owing to vibration or temperature variation if not controlled. Due to the long path lengths, small misalignments of a few millimetres can result in significant movements (centimetres or metres) at the output. Control of the laser beam alignment is therefore a crucial requirement to the success of the facility. This is achieved through automatic beam steering; a closed loop mechanism to compensate for these displacements in near real-time. The motorised actuators will be added to mirror mounts that will be placed at multiple locations along the beam path. Typically each mirror mount will have two actuators.
