Spectroscopic method for measuring the radial component of the magnetic field in cylindrically imploding plasmas

We present a novel polarization-based spectroscopic method developed for measuring the radial component of the magnetic field, Br, in an imploding magnetized-plasma column. The method is based on the combined effects of the Zeeman splitting and the Doppler shift. In the experiment, we use imploding oxygen plasma with a pre-embedded axial magnetic field Bz. Due to the axial non-uniformity of the plasma implosion and the field compression, the Bz lines are bent radially. We measure the magnitude a
