Abstract :
Inductive pickup loops are one of the primary magnetic diagnostics used in modern fusion and pulsed power concepts. To convert the direct voltage measurements from the inductive pickup loop to a measurement of magnetic field or current, the loop voltage must be integrated. Several factors make the integration difficult, especially for long-pulse applications requiring integrator stability for operational timescales from seconds to hours.
