\nFusion energy promises to produce clean and safe el ectricity on a large scale\, but it still faces some challenges.). The fusion gain in a tokamak is directly linked to the density of the pla sma. However\, due to the high temperatures and densities\, it impossi ble to fuel the plasma core in a fusion reactor\, as all neutral parti cles will ionize at the edge of the device. Without any direct fueling in the core of a tokamak\, the plasma density is fully controlled by transport perpendicular to the confining magnetic field surfaces. In t his talk I will show how cross-field transport is dominated by turbule nce in the plasma core by comparing experiments with existing models. These models capture how various types of turbulence influence transpo rt and thus the density profile. While the density profile in the core is fully determined by turbulent transport\, at the plasma edge\, the picture is more complicated. At the edge of the tokamak\, turbulent t ransport effects intermingle directly with fueling through ionization of the surrounding gas. Sustaining a high-density plasma\, which is op aque to neutrals is not dissimilar to a minority navigating the fusion and plasma community. The talk will be interwoven with personal exper iences\, statistics and best practices to achieve a healthy fusion com munity and reduce the opaqueness for minorities to succeed.
