A POWER-BALANCE MODEL OF L-MODE DENSITY LIMIT IN FUSION PLASMAS

Abstract : A 1D cylindrical power-balance model of the radiation density limit gives a unified description of the phenomenon for stellarator, reversed field pinch and L-mode tokamak [P. Zanca et al, Nucl. Fusion 59 (2019) 126011]. The density limit scaling laws for the three different configurations are all derived by combination of just two equations: i) single-fluid heat-transport equation; ii) on-axis Ohm's law with Spitzer resistivity, taken in a suitable limit for the stellarator. Here, we present a refined version of the model, alongside further experimental evidences supporting its successful application.
