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.
Cornell graduate student, Jay Angel, aligns and calibrates the Zeeman Polarization Spectroscopy on the 1 MA COBRA pulsed-power generator optical system using a neon light source.

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.
Sophia will be working in Andrea Schmidt’s group, which is in the National Security Engineering Division of the Engineering Directorate. Sophia will be working on diagnostics (primarily neutron diagnostics, as well as potentially Thomson scattering and spectroscopy) for a dense plasma focus (DPF) on the pulsed-power machine MJOLNIR. The DPF is being developed as a source for neutron radiography. Congratulations Sophia!
LPS Graduate Students create a Plasma Physics Reading Club. Each week a student volunteers to lead a discussion on a plasma physics related article (or textbook sections) of his or her choice. We hope to promote scholarship and exchange of ideas in plasma physics and also just catch up on what others have been working on in the lab. Exampls so far since the club was established are;
Field reversed configurations (review article by Tuszewski)
Thomson scattering (sections in Principles of Plasma Diagnostics textbook)
Plasma transport (review article by Braginskii)
Axial magnetic flux separation (paper by Prof. Charles Seyler – full title: Axial magnetic flux amplification in Hall-magnetohydrodynamic simulations of externally magnetized z-pinches)
Big shout out to Tommy Hentschel for passing his A exam.
Ahmed is in the process of loading the XP machine with the Hybrid X-pinch electrodes. The current work is focused on time resolved source size measurement under high magnification using a fast sweep streak camera.
