Understanding the energy losses mechanism in fusion devices: A summary of recent experiments
Ahmed Diallo, Princeton Plasma Physics Laboratory
The simultaneous achievement of high performance core plasma and highly dissipative boundary plasma is key for future fusion reactors. The critical region of interaction is the edge transport barrier (also known as the H-mode pedestal), which mediates the tension between core and edge, and plays a defining role in the performance of both. Fusion performance in these reactors hinges critically on the efficacy of the edge transport barrier at suppressing energy losses. This talk will highlight current state of research aimed at characterizing and understanding the instabilities localized in the edge of fusion devices as well as challenges for the development of edge models for future devices.
