1. A toroidal fusion reactor assembly comprising:

  • (a) a plurality of toroidal field (TF) coils;

    (b) a plurality of ohmic heating (OH) coils disposed inside the toroid of said TF coils, said OH coils cooled by a cooling fluid;

    (c) each of said OH coils comprising two flat washer-like members placed together and having a common inner radius Ri and an outer radius Ro ;

    (d) an inlet for said cooling fluid to pass to said OH coils;

    (e) an outlet for receiving cooling fluid from said OH coils; and

    (f) each of said OH coils including at least one magnetic coil turn, said coil turn being one of said two flat washer-like members and said coil turn having a plurality of radially outwardly spiralling cooling channels for controlling the passage of cooling fluid through said coil turn, each channel extending from said inner radius Ri to said outer radius Ro in a continually increasing radial amount and extending over a portion less than the circumference of said coil turn,whereby the coil turn cooling characteristics are radially varied.
