Transient radiative bursts have been observed in systematic time-correlation with dust influx across the separatrix in JET ILW campaigns, [1]. Dust influx from PFC materials can produce transient temperature and density perturbations in the SOL. Are such local perturbations detectable by existing diagnostics? Could they be used as an additional monitor for safe operation? Results from the model illustrated here indicate that local densities of dust can produce bursts of acoustic waves in the low-temperature, low-density SOL, that could be detected by existing diagnostics.
In a world increasingly facing new challenges at the forefront of plasma scientific research and technological innovation, CNR and ISTP pledge progress and achieve an impact in the integration of research into societal practices and policy
