Abstract
Disclosed is a segmented toroidal field coil for use in a tokamak-type reactor and a method for forming the coil. Each toroidal field coil winding is segmented into two or more segments with a connection means provided at the end of each segment for electrically connecting the segments together and for joining consecutive adjacent segments. The coil segments are electrically conducting and will, therefore, induce a toroidal magnetic field when its feed points are connected to a power source. The toroidal field coil of the present invention maximizes heat flow from the plasma region of the reactor to the external blanket by eliminating bulky crossover connections from coil to coil that could otherwise restrict the heat flow. The present invention discloses a simple and efficient method for forming a toroidal field coil assembly that eliminates costly final machining such as precision twisting.
