摘要: AbstractA feasibility study for a fast-ion-loss detector in ITER has been carried out. Taking into account the basic requirements measuring magnetohydrodynamic (MHD)-induced fast-ion (fusion-born alpha particles and ions from external heating systems) losses harsh environments expected plasmas, solution based on reciprocating probe installed an equatorial port is suggested. In agreement with previous studies, Monte Carlo simulations of alpha-particle load first wall MHD quiescent plasmas indicate that main will be concentrated below midplane, region blanket module (BM) 15 to BM 18. Orbit tracing thermal analysis, including plasma photonic particle fluxes together nuclear heating, have performed estimate most suitable measurement timing position probe, enabling detection escaping pitch angles ˜0 85 deg. This large velocity space ensures escapin...
