A study of molybdenum influxes and transport in Alcator C-Mod

摘要

A characterization is presented of Mo sources T_Mo, core Mo content N_Mo and their dedpen- dences on the Alcator C-Mod operational regimes. The primary impurity source locations are the divertor, the inner wall and the ICRF antenna limiters. Boronization is used to coat the first wall surfaces with an е folding period of 15-510 discharges.
