Heat loads in inboard limited L-mode plasmas in TCV

Infrared thermography is used in TCV to measure the heat flux deposited onto the graphite tiles of the inner wall. The heat flux radial profile is found to be well described by the sum of a main parallel component and a non negligible cross-field component. The latter accounts for about 20% of the deposited heat flux. The parallel component shows an enhancement around the contact point in all discharges under consideration. Main plasma parameters, such as density, current, elongation and triangularity have been varied, allowing for empirical scalings of the heat fluxes. (C) 2015 Elsevier B.V. All rights reserved.
