Abstract
Official abstract text for this publication.
There is described a central column for a toroidal field coil of a tokamak plasma chamber. The central column comprises a support member extending vertically along a central axis of the central column made from material with high compressive strength, and current carrying elements located radially outward of the support member. The support member is in structural contact with the current carrying elements so as to support them radially against compressive Lorentz stress.
First claim
Opening claim text (preview).
The invention claimed is: 1. A central column for a toroidal field coil of a tokamak plasma chamber, the central column comprising: a support member extending vertically along a central axis of the central column; current carrying elements of the toroidal field coil located radially outward of the support member; a coolant channel within the support member; electrical insulation around each of the current carrying elements; and cooling ribs in thermal contact with the electrical insulation, and extending radially outward from the support member and through the support member into thermal contact with the coolant channel, the cooling ribs comprising an electrically conductive material, wherein the support member is in structural contact with the current carrying elements so as to support them radially against compressive Lorentz stress. 2. A central column according to claim 1 , wherein the electrically conductive material comprises a metal. 3. A central column according to claim 2 , wherein the metal is copper. 4. A central column for a toroidal field coil of a tokamak plasma chamber, the central column comprising: a support member extending vertically along a central axis of the central column; current carrying elements of the toroidal field coil located radially outward of the support member; a coolant channel within the support member; electrical insulation around each of the current carrying elements; and cooling ribs in thermal contact with the electrical insulation, and extending radially outward from the support member and through the support member into thermal contact with the coolant channel, the cooling ribs comprising an electrically conductive material; wherein the support member is in structural contact with the current carrying elements so as to support them radially against compressive Lorentz stress; and wherein the current carrying elements comprise said electrically conductive material. 5. A central column according to claim 4 , wherein the electrically conductive material is copper.
