AB - The National Ignition Facility (NIF) uses powerful lasers to compress targets, to study high energy density physics. Sophisticated diagnostics are placed close to the targets to record the results of each shot. The placement of these diagnostics relative to the target is critical to the mission, with alignment tolerances on the order of 500 microns. The integration of commercial laser-based survey instruments into the NIF control system has improved diagnostic alignment in many ways. The Advanced Tracking Laser Alignment System (ATLAS) project incorporates commercial Faro laser tracker instruments into the diagnostic factory and the target chamber, improving alignment accuracy over prior systems. The system uses multiple retroreflectors mounted on each of the diagnostic positioners to translate to a 6D position in the NIF target chamber volume. This enables a closed loop alignment process to align each diagnostic. This paper provides an overview of how the laser tracker is used in diagnostic alignment, and discusses challenges met by the control system to achieve this integration.
