PEST3
- Abstract
- This is the nonideal (Delta') version of the Princeton
Equilibrium and STability (PEST) suite of codes, which
has been developed since the late 1970s to determine
the linear stability properties of toroidal, magnetically
confined plasma equilibria. PEST3 assumes zero-inertia
for all components of the displacement. The result
is a displacement field that is strongly singular (i.e.
non-square integrable) about rational surfaces. The
leading coefficients of the dominant and recessive
components of the normal displacement are extracted
to form a matching (Delta'-)matrix, which can be used
in a postprocessing stage to determine the nonideal
stability of linear or weakly nonlinear modes. Modes
that fall in this category are the nonlinear resistive
and neoclassical tearing modes for instance, provided
the island width is small compared to the minor radius.
In addition to computing the matching data, PEST3 also
returns a yes/no answer to the ideal stability question.
