Monier-Garbet Experimental scaling law used to determine total C erosion Integration of C-generation discharge per discharge 850 g for 3 first CIEL campaigns ( ) 2200 g from 2002 to 2007 Not taken into account… Erosion on bumpers observed, not quantified Glows discharges (J. Bucalossi et al., JNM (2003) 263) g ( – C) for Disruptions (from C. Grisolia, ITPA & F. Saint-Laurent) ~100/year, g ( – C) UFOs (~450 during DITS) (size from Ne) < 1 g for , negligible Uncertainty of g
