A Magnetic Diagnostic Code for 3D Fusion Equilibria
Authors: Samuel A. Lazerson, S. Sakakibara and Y. Suzuki
Abstract:
A synthetic magnetic diagnostics code for fusion equilibria is presented. This code
calculates the response of various magnetic diagnostics to the equilibria produced by
the VMEC and PIES codes. This allows for treatment of equilibria with both good
nested flux surfaces and those with stochastic regions. DIAGNO v2.0 builds upon
previous codes through the implementation of a virtual casing principle. The code is
validated against a vacuum shot on the Large Helical Device (LHD) where the vertical
field was ramped. As an exercise of the code, the diagnostic response for various
equilibria are calculated on the LHD.
