    In magnetic confinement fusion devices, most of the power across the last-closed flux surface (LCFS) is transported towards the divertor along a narrow channel in the scrape-off layer (SOL). The width of this channel is denoted as lq and extensive experimental studies of the scaling of this parameter are found in the literature (see e.g. [1–4]), however, a theoretical understanding of what constitutes lq is still missing. We therefore investigate the scaling of this SOL power fall-off length by means of numerical simulations. This is done using the HESEL model [5], a four-field 2D drift-fluid model solving for the density, n, generalised vorticity, w omega, electron pressure, pe, and ion pressure, pi, in a domain at the outboard mid-plane.
