Abstract

A test of ripple-assisted neutral-beam injection will be performed on the ISX-B device in 1978-79, using a low-power beam with W//b similar 10 to 20 keV, and possibly also on the TFTR device ca. 1982 with a high-power 80-keV beam. In both cases, the optimal coil configuration for establishing the required vertically asymmetric toroidal-field ripple consists of a pair of trapezoidal current loops located between the TF coils and the vacuum vessel, and bracketing the vertically injected beam. This report describes the design of the ripple coils for ISX-B, the ripple contours in the elliptical ISX-B and circular TFTR plasmas, and the objectives and parameters of the ISX-B experiment. The formation of magnetic islands in the plasma is examined for an arbitrary number of ripple-injection locations.
