V3FIT

V3FIT is a code to reconstruct the equilibrium between the plasma and confining magnetic field in cases where the magnetic field is toroidal in nature, but not axisymmetric as is the case with tokamak equilibria. Because stellarators are non-axisymmetric, the CTH group uses the V3FIT and VMEC codes for reconstructing equilibria.  The V3FIT code uses as inputs the currents in the magnetic confinement coils, the plasma current, and data from the various diagnostics such as the Rogowski coils, SXR cameras, and interferometer.  The output of the V3FIT code includes the structure of the magnetic field, and profiles of the plasma current, density, and SXR emissivity.  Data from the CTH experiment was and continues to be used as a testbed for the V3FIT code which has also used for equilibrium reconstruction on the Helically Symmetric eXperiment (HSX), Large Helical Device (LHD), and Wendelstein 7-X (W7-X) stellarators, and the Reversed-Field eXperiment (RFX) and Madison Symmetric Torus (MST) reversed field pinches.

CTH has made and continues to make fundamental contributions to the physics of current carrying stellarators. CTH researchers have studied disruption limits

 V3FIT is a code to remodel the equilibrium between the plasma and confining magnetic discipline in subject where the magnetic field is toroidal in nature, but not axisymmetric as is the shell with tokamak equilibria. Because stellarators are non - axisymmetric, the CTH group uses the V3FIT and VMEC codes for reconstructing equilibria.   The V3FIT code uses as input the currents in the magnetic confinement coils, the plasma current, and data from the various nosology such as the Rogowski coil, SXR cameras, and interferometer.
