Numerical modelling of steady state fluxes at ITER first wall
Numerical modelling of steady state fluxes at ITER first wall
Plasma parameters in the vicinity of the ITER upper and equatorial ports have been modeled With B2-EIR-ENE code (SOLPS4.3). Erosion rates of Mo and W due to charge-exchange neutrals and deposition rates of C and Be have been estimated. The modelling results can be used for estimating the lifetime of...

Plasma parameters in the vicinity of the ITER upper and equatorial ports have been modeled With B2-EIR-ENE code (SOLPS4.3). Erosion rates of Mo and W due to charge-exchange neutrals and deposition rates of C and Be have been estimated. The modelling results can be used for estimating the lifetime of the first mirrors of optical diagnostics and, to some extent, for evaluating the lifetime of metallic wall. Maximum calculated sputtering rate of Mo at the outer mid-plane is approximate to 0.005 nm/s, maximum calculated net deposition rate of Be is approximate to 0.01 nm/s. The modelling shows that gas puff can lead to significant local increase of erosion and decrease of deposition, ensuring the net erosion conditions for C and Be. (C) 2009 Elsevier B.V.
