Project background
THE MEGAJOULE LASER (LMJ), LOCATED NEAR BORDEAUX IN FRANCE, WILL BE THE MOST ENERGETIC LASER IN THE WORLD AND WILL SIMULATE NUCLEAR FUSION.
AT THE CENTER OF A 10-METER DIAMETER EXPERIENCE, 176 LASER BEAMS CONVERT TO A 2 MM-DIAMETER DEUTERIUM-TRITIUM TARGET.
CUSTOMER REQUEST
CEA needs a high accuracy positioning system (1 µm resolution) to adjust the micro-target at the centre of the test room and ensures the convergence of the 176 laser beams towards the centre.
Project specifications
■ High accuracy positioning
■ Harsh environment positioning: vacuum and radiations
■ 1 µm positioning accuracy
