Abstract: Techniques are described for automatically removing and replacing components, including a vacuum vessel, from a tokamak. The inventors have recognized that schemes for automatically removing and replacing components from a tokamak should preferably be simple (e.g., using proven equipment to perform a series of non-mechanically complex tasks) and have a very low risk of damaging components. Techniques described herein may include splitting a tokamak into multiple pieces, separating the pieces, and removing the now separate pieces of the vacuum vessel from within the pieces of the tokamak. A new vacuum vessel can be inserted in multiple pieces and the tokamak rejoined to complete the replacement process.

Abstract: Described is a cable comprising a plurality of high temperature superconductor (HTS) components, a plurality of electrically conductive segments extending along a length of the cable, each of the plurality of electrically conductive segments comprising one of the plurality of HTS components, and an electrically insulating material arranged between adjacent ones of the plurality of electrically conductive segments.
