Vacuum positioning

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 WILL CONVERT TO A 2 MM-DIAMETER DEUTERIUM 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.
