Linear coil for measuring fast distributed pulsed current

Abstract
Describes the theory, design and performance of a linear coil used to measure distributed current pulses. The linear-wound coil acts as a delay line. Its response to transient signals is studied for a generic excitation and for various terminating impedances. The probe rise time is less than 1 ns, the attenuation is about 5.3 mV A-1 and it can record currents up to tens of kA.
