Analysis of sweeping heat loads on divertor plate materials
The heat flux on the divertor plate of a fusion reactor is probably one of the most limiting constraints on its lifetime. The current heat flux profile on the outer divertor plate of a device like the International Thermonuclear Experimental Reactor (ITER) is highly peaked with narrow profile. The peak heat flux can be as high as 30-40 MW/m 2 with full width at half maximum (FWHM) of the order ...
متن کاملMaterials research under ITER-like divertor conditions at FOM Rijnhuizen
At FOM Rijnhuizen, linear plasma generators are used to investigate plasma-material interactions under high-density (610 m!3), low-temperature (65 eV) plasma bombardment. Research into carbon-based materials has been focused on chemical erosion by hydrogen plasmas. Results from plasma exposure to high-flux (>10 H/m s) and low-temperature hydrogen plasma indicate silicon carbide has a lower rela...
متن کاملARIES-RS divertor system selection and analysis
The ARIES-RS divertor system is selected and analyzed. A radiative divertor approach using Ne as the radiator is chosen to reduce the maximum heat flux to B6 MW m. A 2 mm W layer is used to withstand surface erosion allowing a design life close to 3 full-power-years. This W coating on the V-alloy structure is castellated to meet structural design limits. A detailed description of the calculated...
متن کاملAn evaluation of kinetic eects in the DIII-D divertor
Under certain conditions, high temperature electrons diusing across the separatrix near the midplane can propagate to the divertor without collision and produce a high energy tail in the electron distribution function near the separatrix. We evaluate a kinetic criterion along the ®eld using measurements from divertor Thomson scattering and compare temperature measurements from target plate Lan...
