Fielding the LANL third-generation Gas Cherenkov Detector (GCD-3) at the National Ignition Facility (NIF) revealed an
array of complex engineering challenges. Fielding the GCD-3 Detector in a 3.9 meter re-entrant Well on the NIF Target
Chamber required the development of a specialized detector deployment system named the WellDIM3.9m Diagnostic
Manipulator (WellDIM). The most stringent design requirement entailed a no-load/no-contact condition with the Well, which
dictated that all seismic loads be transferred to the Target Chamber port flange. The WellDIM transports the GCD-3 into the
Well at a distance of 3.9m from Target Chamber Center. The GCD-3 Detector, outfitted with additional shielding to mitigate
higher NIF backgrounds, will serve as a prototype for the future, heavily shielded “Super-GCD”.
