  • Abstract
    The results of the investigation of retention and thermal desorption of hydrogen isotopes of B4C coated RGT (a recrystallized graphite with high thermal conductivity, 600 W/mK) after the exposure to high heat flux in the divertor strike point region of DIII-D using the DIMES sample exchange system are reported. It is shown that the material is very promising for plasma facing elements of tokamaks
