Replacing a Grating Debris Shield
Target Area Coordinator Kevin Hood replaces a grating debris shield (GDS) in a NIF final optics assembly. The GDSs protect the other final optics from target debris and diffract about 0.1 percent of NIF’s ultraviolet light into an energy diagnostic system. More than 90 percent of damaged GDSs are repaired in the Optics Mitigation Facility and returned to service. Credit: Juan Soto
