Characterising Dust in JET with the New ITER-Like Wall
The results from several studies dedicated to the characterisation of in-vessel dust in JET with he new ITER-like wall (ILW) are reported here. These studies collectively aim to gain insight into the nature of JET's in-vessel dust and its impact on current plasma operations. The techniques used here include the analysis of light scattered from dust mobilized by disruptions and the study of plasma impurities thought to be associated with dust via VUV spectroscopy, together with the analysis of plasma events recorded by JET's camera systems. Some results from a recent in vessel inspection (which included detailed photo surveys of plasma facing components and dust collection) and results from the numerical modelling of the plasma-dust interaction using the DTOKS and STRAHL codes are also presented.
