      abstract     = {The first mirrors of ITER diagnostic systems are the most
                      vulnerable ones since they are directed to the plasma and
                      are subjected to erosion and intensive impurity deposition.
                      To keep their optical performance and maintainability,
                      single crystalline molybdenum and rhodium have been
                      considered as mirror materials, subject to intensive
                      investigations including $R\&Ds$ and mirror cleaning
                      studies.The paper presents specific design and structural
                      issues of the first mirror of 300 mm in the size considered
                      for the ITER core charge exchange recombination spectroscopy
                      (cCXRS). Such a large mirror can be assumed as a generic one
                      for solid middle (size) mirrors (up to 100 mm in diameter)
                      and for composed large mirrors (diameter >150 mm) that are
                      potentially made of an assembly of smaller pieces.The main
                      design aspects like the first mirror material, the cooling
                      capability of passively and actively cooled mirrors and the
                      mechanical behavior of rhodium and molybdenum mirrors
                      composed of single crystals pieces (i.e. plates and tiles)
                      have been addressed and studied. The mirror design is
                      supported by extensive structural and multi-field analysis.},
