Jason graduated from Cornell in December 2021. Jason will stay on at Cornell as a PostDoc doing research using the 3D Perseus code with the improved 13-Moment transport model to simulate COBRA gas puff implosions. In particular, interest in how the transport model impacts the implosion dynamics and the conditions at stagnation.

Originally from La Crescent, Minnesota, a small town nestled alongside the Mississippi River. Growing up I spent my time outside school in the woods, on the water, or at the local hardware store where I worked. In my academics, I enjoyed the sciences and mathematics and also enjoyed the industrial arts such as woodworking, metalworking, and other trades. My combined interests lead me to study engineering physics at the University of Wisconsin-Platteville, where I received my bachelor’s in December 2019. During my undergraduate studies I had multiple opportunities to work in plasma science, which I quickly discovered to be a rich blend of engineering, physics, and chemistry.
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.
