Aligning the Target Positioners

NIF operators acquired simultaneous positioning stability for all three NIF target positioners—the TarPos, the cryogenic TarPos, and the dual-purpose Target and Diagnostic Manipulator (TANDM)—in the Target Alignment Sensor (TAS) during the December 2016 facility maintenance and reconfiguration (FM&R) period. This marked the first time three targets were simultaneously tested in the TAS, which is used to align NIF beams and targets to a common referenced coordinate system. The test was among nearly 360 tasks performed over the two-week FM&R period.
