In his last run on COBRA he tested the possibility of getting faraday rotation measurements of the azimuthal magnetic field distribution in our gas puff z-pinches. While still working on some of the analysis, here is a picture that confirms we are seeing faraday rotation. For the images with -5 degree selection angle, the left side of the pinch darkens as the polarized laser light rotates towards the extinction angle while the right side brightens. Flipping the selection polarizer angle, we see that the dark side is now on the right side of the pinch.
