Magnetic field simulation of hourglass-ohmic heating transformer-driven Novillo Tokamak

The numerical study of the divers magnetic field configurations in the Novi llo Tokamak developed by means of the CAMTOK code is presented to illustrat e not only the application of classical analysis to a specific case but als o a straightforward technique to develop magnetic design codes. Algorithms and results in the case of the ohmic heating transformer, toroidal, and equ ilibrium systems are presented. On the basis of CAMTOK simulations and meas ured values, stray components of the fields are identified and suppressed, leading to the redesign of the original concept of the Novillo tokamak into its current operating configuration.
