Techniques for source-region EMP experiments at AURORA

This memo describes reliable measurement techniques for determining source-region EMP parameters in the AURORA room. The general principles involved in each measurement, the interference effects, and specific design considerations for the AURORA environment are discussed. These measurements include the determination of the electromagnetic fields, the current densities, the air conductivity and the induced currents on a conductor. The interference effects, as they relate to each of these measurements, occurring from Compton transfer currents, ionization-induced conduction, shield currents and photo-induced cable currents are also discussed.
