Alessandro Bortolon

Alessandro Bortolon is currently a Research Physicist with the Princeton Plasma Physics Laboratory, Princeton, NJ, USA, working on the DIII-D tokamak in San Diego, leading the research on the effects of actively injected, nonrecycling impurities on key aspects of fusion plasmas. He completed his doctoral research at the Swiss Federal Technical Institute, Zürich, Switzerland, focusing on measurement of intrinsic plasma rotation, momentum transport, and spontaneous rotation reversals in the TCV tokamak. He subsequently conducted his post-doctoral research at PPPL, on the National Spherical Torus Experiment (NSTX), turning his interest to energetic particle physics, in particular fast-ion transport and fast-ion-driven instabilities in presence of externally applied magnetic perturbations. His present research on DIII-D focuses on the use of controlled injection of low-Z, nonrecycling impurities in form of solid granules or powder, as innovative tools to improve plasma wall interaction, mitigate plasma instabilities, or address the issue of divertor power exhaust.
