A new laser-Doppler velocimeter (LDV) for high speed flow measurements (three-dimensional flows with speeds greater than 610 m/s) is being developed based in-part upon an existing low speed instrument capable of high resolution, near surface velocity vector measurements. The key technology for the instrument is a sub-miniature laser-Doppler velocimeter (SMLDV); a similar low-speed version of wh...

The Laser Applications at Accelerators network (LA3NET) is a pan-European project that has received 4.6 M€ of funding from the European Union's 7th Framework Programme. It closely links research into lasers and accelerators to develop advanced particle sources, new accelerating schemes, and in particular beyond state-ofthe-art beam diagnostics. This contribution summarizes the research achievem...
