Engineering Design Studies for the Quasi-Omnigeneous Stellarator
Abstract
The proposed Quasi-Omnigeneous Stellarator, QOS, is a compact stellarator experiment with a non-axisymmetric, helical-axis magnetic configuration. The nominal parameters are R = 1 m, < α > = 0.28 m, B = 1 T, and 1-s pulse length. The primary challenge for the engineering design is to find cost effective methods for fabrication and assembly of the modular coil set and the vacuum vessel. The modular coils use flexible cable conductor wound on a form and vacuum impregnated with epoxy. The coil form consists of a stainless steel casting with a precision winding cavity and includes support features that allow the coils to be connected into an integral structure. The vacuum vessel is a welded stainless-steel shell press formed in segments and welded together. The vessel has 6 identical sections and the modular coils are assembled over the vessel sections. The status of the engineering design, fabrication process selection, and analysis for QOS will be presented.
