The main experimental results related to the problems associated with in-vessel mirrors in ITER obtained with the DSM-2 facility at the Kharkov Institute of Plasma Physics over the past few years are described and discussed. Mirrors made from various polycrystalline (Be, Al, SS, Cu, Mo, Ta, W) and single crystal (Ni, SS, Mo, W) metals, metal films (Be, Cu, Mo, Rh) on different metal substrates (V, SS, Cu, Mo), and an amorphous alloy (ZrTiCuNiBe) have been studied. In addition, the behavior of protective oxide coatings under plasma bombardment has also been analyzed.
