      abstract     = {The ITER core charge exchange recombination spectroscopy,
                      which contains five in-port optical mirrors, is intended to
                      transfer the visible light emitted by interaction of the
                      plasma with the diagnostic neutral beam to the corresponding
                      spectrometers. The first mirror (M1) is a key and the most
                      vulnerable component of the diagnostics. In order to provide
                      the required mirror lifetime, maintainability and structural
                      integrity, M1 is composed of special materials, i.e. it is
                      made of a thin 1 mm single-crystal rhodium (ScRh) plate
                      diffusion bonded to a specially matched tungsten-copper
                      substrate. A rhodium nanocrystalline coating (NcRh) can be
                      an option.The paper presents the evolution of the M1 design
                      developed for the optical layout of 2018. M1 is adjustable
                      and cleanable with about 100÷500 procedures of 60 MHz
                      plasma discharge. The mirror design is supported by
                      multifield thermal, electromagnetic and structural analyses
                      and uses experimental data of $R\&Ds$ made by
                      Forschungszentrum Juelich, Germany. The study confirms the
                      working capacity of the developed mirror solution.},
