| Popis: | Some aspects of the applicability of the magnetic-probe technique in high-power pulsed discharges are analyzed. The influence of an electron beam and an intense X-ray yield of (~1 TW/cm2), which result from the compression of high-current plasma in the interelectrode gap of a Z-pinch discharge, on the correctness of measurements using magnetic-field probes was studied. We considered the use of multilayer shells as a method for protecting the sensing element of a magnetic probe. The results of experimental testing of probes of a new design in experiments with wire assemblies on the Angara-5-1 facility at discharge currents of up to 4 MA are presented. Experiments on the Angara-5-1, PF-3, and PF-1000 high-power electrophysical facilities show the effect of the shape and material of the probe shell on the perturbation of plasma that flows around a probe and, as a consequence, on the accuracy of the magnetic-field measurements. |
