Review of laser mega joule target area: Design and processes

Abstract
The French Laser Mega Joule (LMJ) target area is currently designed to achieve ignition and significant fusion gain in the laboratory. Design studies for target equipments are well advanced, target chamber and target area frame (concrete) is even started.

A detailed overview of the target area equipments is presented: target chamber, frame, diagnostic inserter manipulator, final optic assembly, dual diagnostic and laser reference, non cryogenic target positioner. Recent technical and architectural choices are detailed including safety transfers and alignment processes (target, laser and diagnostic).

All these target equipments allow to optimize shot chronogram, from target metrology to the shot, including calibration process.
