The purpose of this calculation
is to evaluate bake-out strategies for NSTX upgrade that will produce
acceptable temperatures at the tile surfaces (i.e. temperature approaching
350C and not damage insulation or structural components, particularly near
the PF1B mandrel/case.

DRAFT
|
The
benchmark instrumentation will produce data that will be evaluated after a shot
is complete. The results will then be compared with the DCPS algorithm
predicted values. It is the purpose of this calculation to evaluate the
instrumentation data as it becomes available.

includes additional algorithm calculations here. The algorithms have been
incorporated into a True Basis code that can run the algorithm evaluations
for the 96 GRD design point equilibria and other provided scenarios. This
can be used to check the DCPS implementation or find limiting equilibria
among the provided 96.
