As part of the French Inertial Confinement Fusion (ICF) experiments, cryogenic target assemblies (CTAs) for the Laser M├ęgajoule (LMJ) program are manufactured and filled at CEA Valduc (Dijon) in tritium facilities. They will be moved at about 20 K into a transport cryostat for cryogenic targets, and will be driven from CEA/Valduc to CEA/CESTA (Bordeaux).

This paper deals with the description of the tritium facilities for the LMJ cryogenic target.

Twelve gloveboxes are needed to furnish 6 CTAs at the same time. These twelve gloveboxes make a relative independent set in the Valduc tritium building and house equipment to prepare the CTAs and the different vacuum vessels, to store and purify gas, to fill and cool the targets and transport them at cryogenic temperature.
