3. DESCRIPTION OF PROBLEM OR FUNCTION

TOKMINA finds the minimum magnetic field, Bm, required at the toroidal coil of a Tokamak type fusion reactor when the input is beta(ratio of plasma pressure to magnetic pressure), q(Kruskal-Shafranov plasma stability factor), and y(ratio of plasma radius to vacuum wall radius: rp/rw) and arrays of PT(total thermal power from both d-t and tritium breeding reactions), Pw(wall loading or power flux) and TB(thickness of blanket), following the method of Golovin, et al.
TOKMINA-2 finds the total power, PT, of such a fusion reactor, given a specified magnetic field, Bm, at the toroidal coil.

4. METHOD OF SOLUTION

TOKMINA: the aspect ratio(a) is minimized, giving a minimum value for Bm. TOKMINA2: a search is made for PT; the value of PT which minimizes Bm to the required value within 50 Gauss is chosen.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Input arrays presently are dimensioned at 20. This restriction can be overcome by changing a dimension card.

6. TYPICAL RUNNING TIME

TOKMINA: approximately 30 seconds for 100 sets of input values.
TOKMINA-2: approximately 1 minute for 700 sets of input values.

7. UNUSUAL FEATURES OF THE PROGRAM

Output for each set of input values are TB, Bt(toroidal magnetic field on the minor axis), R(major radius of the toroid), rp, Rm(distance between the major axis and the blanket in the midplane), n(density of the plasma) and I(plasma current). These values, as well as Bm and PT may be studied as a function of blanket thickness.
