abstract = {Light-based diagnostic systems of fusion reactors require
optical mirrors to channel light through the structures
surrounding the plasma. With increasing plasma volume, power
and plasma burn time, the environmental conditions grow more
demanding and new requirements arise. In this dissertation,
the design of optical mirrors inside the vacuum chamber of
the prototype reactor ITER (Latin "the way") and future
fusion power plants are investigated.Comparing the state of
the art with the boundary conditions close to the fusion
plasma, existing mirror designs and choices for the
reflective surface are evaluated. For the design, it is not
the individual boundary conditions that are critical, but
rather, their combination and the resulting interactions.
Drawing from the existing designs, possible realizations for
central functionality are discussed. Included in the
discussion are substrate choice, mounting, adjustment and
thermal contacting as well as positioning of the mirror
assembly compatible with hot cell maintenance.Building on
the general discussion, mirror concepts for the charge
exchange recombination spectroscopy (CXRS) diagnostic system
for the ITER plasma core are proposed and simulated. In
addition, prototypes are manufactured and tested to assess
critical aspects of the proposed design. Testing includes
positioning by pins, manufacturing of a stainless steel
substrate with fluid channels adapted to the mirror shape,
and tests with an SiO$_2$/TiO$_2$ dielectric coating under
selected ITER conditions.As a result of the work, the fusion
reactor mirror design considerations given in the principal
design discussion can be used as a basis for other
diagnostic systems as well. In the case of the core CXRS
mirror concept for ITER, the basic suitability was shown and
critical topics were identified where additional work is
necessary.},
