Title: Sensor for detecting changes in magnetic fields

Abstract

A sensor for detecting changes in the magnetic field of the equilibrium-field coil of a tokamak plasma device comprises a pair of bifilar wires disposed circumferentially, one inside and one outside the equilibrium-field coil. Each is shorted at one end. The difference between the voltages detected at the other ends of the bifilar wires provides a measure of changing flux in the equilibrium-field coil. This difference can be used to detect faults in the coil in time to take action to protect the coil.
