Abstract
Small electrodes were installed in the outer-midplane edge of NSTX to attempt to control the local width of the scrape-off layer (SOL) by creating an outward E(pol)xB flow. When the applied voltage between electrodes was 90 V, the density between these electrodes increased by a factor of 3-10 over a radial width of similar to 4 cm. Thus a local control of the SOL plasma density was obtained. (C) 2009 Elsevier B.V. All rights reserved.
