Modelling the pumped divertor

  • 1. Commission of the European Communities, Abingdon (UK). JET Joint Undertaking

Description

The aim of the axisymmetric pumped divertor proposed for the New Phase of JET has two aspects: firstly, to control the back-flow of impurities from the target plates towards the main plasma; and secondly, to limit the heat load on the target plates and, hence, their erosion. To achieve this aim it is proposed: firstly, to entrench the impurities in a forced flow of plasma directed along the open magnetic field lines in the scrape-off-layer towards the target plates; and secondly, to reduce the plasma temperature at the target plates by radiating a substantial fraction of the power flow in the vicinity of the target plates. Modelling studies of impurity control and radiation in the JET pumped divertor configuration are reported. (author)
