Characterization of QSPA plasma streams in plasma - surface interaction experiments: simulation of ITER ELMs
Experimental simulations of ITER ELMs with relevant surface heat loads (energy density up to 2.4 MJ/m² ) have been performed with a quasi-steady-state plasma accelerator QSPA Kh-50. Additional shielding effect has been registered during irradiation of the combined carbon–tungsten (C–W) surfaces. Cor...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Experimental simulations of ITER ELMs with relevant surface heat loads (energy density up to 2.4 MJ/m² ) have been performed with a quasi-steady-state plasma accelerator QSPA Kh-50. Additional shielding effect has been registered during irradiation of the combined carbon–tungsten (C–W) surfaces. Correlation between mass losses and thresholds of erosion products ejection has been analyzed depending on the surface heat loads. For heat load below cracking threshold mass losses are caused by physical spattering. Splashing of liquid material is registered for heat load exceeding the melting threshold. |
