Digital Coil Protection System for the National Spherical Torus Experiment Upgrade
Authors: R.E. Hatcher, et. al.
Abstract:
An upgrade to the National Spherical Torus
Experiment (NSTX) is currently in progress. The NSTX Center
Stack Upgrade (NSTX-U) experimental device has an operating
space that is both larger and more complex than that of the
original NSTX. The mechanical integrity of some machine
components can be compromised both by the instantaneous
values of combinations of magnet currents and as a result of the
time histories thereof. An upgrade to the existing protection
systems and methodology is required to allow for both safe and
effective use of the expanded operating space. A Digital Coil
Protection System (DCPS) is planned as a major component of
an upgraded Coil Protection System (CPS).
