Impurity transport studies in multiple helicity and enhanced confinement QSH regimes in RFX-mod

The most recent impurity transport studies in RFX-mod are presented. Results from enhanced confinement quasi-single helicity (QSH) and multiple helicity (MH) are compared. The transport parameters are determined by comparing a 1-dimensional collisional radiative simulation with experimental spectroscopic data. Transport parameters obtained for Ni particles injected by the laser blow-off method are described and discussed in relation to results from Ne injection and previous studies.
