Abstract [en]

Dust injection experiments performed at Magnum-PSI are used to benchmark ion drag and heating models used in the dust tracking code DTOKS using HERMES simulated background plasma. Dust particles follow similar trajectories with a period of free-fall under gravity reaching temperatures in excess of Td > 2500 K followed by deflection in the ion flow and exiting with a constant velocity of v = 7:61:4ms-1. Utilising this benchmark of the DTOKS code, investigative simulations of breakup events observed in JET. Simulations incorporating this effect reproduce the expected lifetimes and qualitative structures of observed trajectories in JET, providing an attractive technique for mitigating transport of large impurities into the core plasma.
