These locations were chosen based on design considerations and their tendency for high stresses. Of these locations, five were found to be consistently dominant. If the insulation shear stresses are found to be acceptable at these five locations, then the insulation shear stresses are considered acceptable everywhere. The NSTX CPC is comprised of stress coefficients representing a variety of  unit value current conditions including the following: " 1ka in the TF " plus or minus 1ka in the OH in the presence of 1ka in the TF " plus or minus 1ka in PF1a (upper and lower) in the presence of 1ka in the TF " 1ka in PF1b in the presence of 1ka in the TF Once currents are provided to the CPC for each coil, the coefficients associated with these unit currents are scaled and followed by linear superposition to generate combined stresses. The effects of thermal stresses are added to these totals to create the complete stress states. The default thermal condition in the CPC is EOFT for high field currents (TF=71.16ka, OH=-22.1ka, PF1a=2ka). These coefficients can be scaled to roughly represent an EOFT low field current condition (TF=35.56ka, OH=24ka, PF1a=15ka) by using a scaling factor of 1.3. Any other thermal conditions would necessitate additional thermal analysis. The CPC itself/ =!"#$% is in the form of an MS Excel spreadsheet.

The OH and PF coils follow below. Note that each includes  TF in its label. This is because the OH and PF coils will not generate forces in the center stack TF leg insulation without the presence of a TF field. Accordingly, the CPC coefficients were developed for unit currents in these coils in the presence of a unit current in the TF. Appropriate scalings and summations are performed by the CPC. For the OH and PF1a coils, a separate set of stress coefficients were developed for both positive and negative currents in each. If a positive current is desired, enter the current, in kiloamps, in the cell to the right of the appropriate coil label. The negative current cell for that coil should either be left blank or else enter a current value of zero. Do the opposite if a negative current is desired. All currents are entered into the CPC as positive numbers. For example, to apply  24ka to the OH, enter  24 (positive number) in the cell to the right of the coil ID label  TF, -OH . Leave blank or enter  0 in the cell to the right of the coil label  TF, +OH .
