Current measurement by Faraday effect on GEPOPU

摘要: The design and calibration of an optical current sensor using BK7 glass is presented. based on the polarization rotation by Faraday effect. GEPOPU a pulsed power generator, double transit time 120ns, 1.5 Ohm impedance, coaxial geometry, where Z pinch experiment are performed. measurements were performed at Optics Plasma Physics Laboratory Pontificia Universidad Catolica de Chile. verdet constant for two different materials was obtained He-Ne laser. values within experimental error bars published in literature (less than 15% difference). Two geometries tried. We present preliminary results one geometries. agree measurement with those means Spice simulation generator. Signal traces completely noise free.
