XPLASMA
 Abstract
The xplasma software offers a representation standard
for plasma MHD equilibria and parameter profiles. Layered
over efficient spline interpolation softare pspline , xplasma consists of a two
sets of routines:
 eqm* routines for
setting up the equilibrium, profiles, scrapeoff region
definition and limiter specification
 eq*
vectorized routines for retrieving information derived
from the set up:
 coordinate transformations
between magnetic coordinates, cylindric coordinates
and cartesian coordinates.
 metric tensor.

field vector and field gradient tensor.
 plasma
parameter profiles and gradients.
The "core
plasma" consists of a bicubic spline "inverse equilibrium"
representation R(rho,chi),Z(rho,chi) and a set of 1d
plasma parameter splines including (at least) g and
psi to complete the equilibrium field specification.
Several options are provided for the specification
of "limiter" or "vessel wall" geometry and creation
of a "scrape off layer" plasma in the space between
the core plasma and the limiter or vessel wall. Mechanisms
are available for setting up rectilinear (R,Z) grids
that cover both the core plasma and the scrape off
layer, over which bicubic Hermite representations of
the field and plasma parameters can be built. Then,
the xplasma "eq*" interpolation routines can be used
to efficiently provide all data needed for such physics
modules as RF ray tracers or neutral beam deposition
models. Physics modules can operate in (R,Z) or (rho,chi)
space as appropriate.
