摘要: The isotope effects of ablation processes in fusion plasma for five combinations solid isotopic hydrogenic pellets H2, HD, D2, DT, and T2 have been studied the first time to our knowledge. results show that modifications caused by pellet erosion speeds range from 1 hydrogen down 0.487 tritium are not negligible rate calculations. These can lead deeper mass deposition improved core fuelling efficiency.
