Summary
The calculation of energy, power, current and voltage requirements of the coils in a tokamak poloidal field system is a common design and analysis problem. The calculation of all circuit parameters, given a sufficient set of inputs, such as a program of current vs. time, along with coil dimensions, is straightforward. However, the construction of a general-purpose code is nontrivial. Several design decisions and physical insights are required, in order to program the coil currents and voltages. It is thus frequently difficult for one investigator to duplicate the design and analysis results of another, using a different code. A further, purely technical barrier, is that the display of calculated parameters in a manner that easily permits the selection of the number of turns for each coil, and the allocation of rectifiers, dump resistors and switches involves a large amount of graphics postprocessing and typesetting, which has not previously been completed. There are also a number of important parameters that can be calculated easily by the use of circuit theory that are usually neglected, including the radial and vertical forces on each coil, before or after a disruption, at each moment in time. The purpose of the code described below is to calculate everything of any design importance that can be deduced through circuit theory, to display the results in a comprehensive, but easy to use format, and to retain enough flexibility in inputting to permit collaboration with other groups.
