Paper Abstract

In pulsed power research, controlled fusion experiments, high-explosives-related research, and other similar undertakings, it is often necessary to measure large pulsed electric currents. The pulses can be large enough to distort conventional, electrically-conducting sensors, such as Rogowski loops. Furthermore, the measurements must frequently be made in the presence of electromagnetic interference (EMI) noise. Optical sensing of the magnetic field surrounding the current is a way to reduce or eliminate both of these problems', and in addition it can provide the other benefits of photonics recording, such as improved bandwidth and reduced cost per channel. The sensing methods developed and used for large current pulses are also finding their way into the smaller-pulse regime.
