Abstract

Edge plasmas in the divertor configuration were studied on the COMPASS tokamak. The dependence of the decay length of the parallel heat flux q|| was measured at different values of plasma current and line-averaged density. We have found that q|| decreases with both the plasma current and the line-averaged density, which is in agreement with previous results achieved on the JET tokamak.
