The CLISTE
interpretive equilibrium code solves the Grad-Shafranov equation for
regularized source
profiles under the constraint that a least squares fit to a set of experimental
signals is
obtained. The code developed from the Garching Equilibrium Code, whose
functionality has
been extended to enable predictive or interpretive modes of operation.
CLISTE can run in
a comprehensive slow mode where the measurements may depend
nonlinearly on the
free parameters, or a more restricted fast mode (whose algorithm is similar
to that of the
well-known EFIT code) where the relationship between free parameters and
measurements must
be linear. Novel features of the code include the ability to handle scrapeoff
layer currents
(assuming ideal MHD force balance) and confidence band calculations for
profile quantities.
Results are illustrated by a sample ASDEX Upgrade equilibrium.
