Abstract:

The magnetic field distribution in a Z-pinch, can be used to infer the currentsflowing in the pinch and study the stability during the implosion phase. Faradayrotation techniques are too insensitive for measurements during the run-in phase.Similarly, it is difficult to infer the Zeeman splitting from spectrally resolvedline profile when the splitting is much less than the absorption line width d.HY-Tech proposes to adapt an astrophysical technique, to infer the Zeeman splittingfrom the intensity difference of the right and left circularly polarized componentsobserved along the magnetic field lines. Measurements are made with a monochrometerset for a single wavelength, d/2 from line center, and a polarimeter to spatially separate the two circularly polarizedcomponents. This system can be used to spatially resolve the magnetic fielddistribution in one dimension (either radially or axially) as a function of timeusing a streak camera. The anticipated 20 point spatial resolution combined withoptical magnification will be adequate for studying the Rayleigh-Taylor and otherinstabilities in the imploding sheath, current commutation between the inner andouter arrays in a nested load, and load currents in magnetic pulse compressionexperiments.Can be used to measure space and time resolved magnetic fields in plasma radiationsources, ion diode and plasma opening switches to study physical processes occurringthere. Also a time resolved version can be used as a non-intrusive current monitor.
