[en] This paper presents briefly highlights of the Eighth Symposium held at San Francisco, 13-16 November 1979, on Engineering Problems of Fusion Research. (Plasma heating, plasma diagnostics, environment and safety programmes, impurity control, fuelling systems, power supplies and magnet technology)
[en] Position control of the plasma in FED or in any reactor type of magnetic toroidal confined fusion machine becomes more of an engineering challenge than the present day plasma experimental devices. This paper briefly describes the structural features which play a dominant role in effecting position control and emphasizes the differences associated with present experimental devices and reactor relevant machines. It outlines the features of startup and disruption to describe their interdependence in determining the design requirements for control. An explanation of the scope of this study is provided with the procedures established to investigate position control requirements. The assumption made and a description of the specific components of the structures which were included in the studies are given. The present FED results and conclusions are then presented
[en] The Super-X Divertor (SXD), a robust axisymmetric redesign of the divertor magnetic geometry that can allow a fivefold increase in the core power density of toroidal fusion devices, is presented. With small changes in poloidal coils and currents for standard divertors, the SXD allows the largest divertor plate radius inside toroidal field coils. This increases the plasma-wetted area by 2-3 times over all flux-expansion-only methods (e.g., plate near main X point, plate tilting, X divertor, and snowflake), decreases parallel heat flux and hence plasma temperature at plate, and increases connection length by 2-5 times. Examples of high-power-density fusion devices enabled by SXD are discussed; the most promising near-term device is a 100 MW modular compact fusion neutron source 'battery' small enough to fit inside a conventional fission blanket.
