Paper Abstract
The Kirkpatrick Baez Optic (KBO) diagnostic designed for the National Ignition Facility (NIF) requires very
precise alignment between four pairs of mirrors that make up four x-ray imaging channels. Furthermore, the
overlapping image axis of the four pairs must be aligned to within a 50 μm radius of the NIF target center. In
order to achieve this the diagnostic utilizes a telescoping snout that when extended, locates the mirrors at the
end of a Diagnostic Load Package (DLP), cantilevered more than three meters out from its bolted connection
points. Discussed in this paper are the structural challenges and the mechanical design solutions that were
implemented to achieve the ±50 μm pointing accuracy. During an Inertial Confinement Fusion (ICF) experiment,
the KBO diagnostic will be 117 mm away from the extremely high impulse, target implosion shock wave, which
requires a unique approach to protecting the sensitive optics which will also be discussed.
