ALT-3 and R-Damage are experiments to be executed in collaboration between LANL and VNIIEF personnel. They are planned to be fielded in Sarov, Russia at VNIIEF. Both experiments employ Russian explosively driven pulse-power systems to generate a pulse of electrical current that is used to drive the experiment. The current pulse will be measured with Faraday-rotation fiber-optic loops. Using this well known technique, the change in the current enclosed by the loops is determined by measuring the change in the magnetic field integrated along the fiber-optic loop by detecting the Faraday rotation of linearly polarized light traveling through the fiber. The amount of polarization rotation of the light is related to the integrated magnetic field and therefore the enclosed current (Ampere's law) through the Verdet constant which for the optical-fibers used in this experiment has been determined to within 1 %. The presentation describes how the technique will be employed in the R-Damage experiment.
