Section: claims

1. A device for electrical connection of internal elements of a reactor chamber to a vacuum vessel in a nuclear fusion reactor comprising:a pair of flanges, anda plurality of lamellar electrically conductive elements disposed in lamellae between the flanges;wherein,the conductive elements and the flanges are a single continuous integral unit,each electrically conductive element has an undulate shape and includes bends between surface portions with differently directed normals,the plurality of electrically conductive elements are arranged in layers between the flanges, andeach electrically conductive element has thickenings at the bends between the surface portions with differently directed normals and at transition areas where the electrically conductive elements transition to the flanges. 2. The device of claim 1, wherein the device is made from a single blank of an electroconductive alloy. 3. The device of claim 2, wherein the electrically conductive elements are formed by making profiled slots in a central section of the single blank by electric erosion machining. 4. The device of claim 2, wherein the electrically conductive elements are formed by making profiled slots in a central section of the single blank by hydro-abrasive treatment.
