Experimental Investigation of Plasma-Electrode Interactions on the ZaP-HD Flow Z-Pinch Device
Committee
Uri Shumlak (Chair), Justin Little, Eric Meier, Saadia Pekkanen, Carl Knowlen
Abstract
The electrodes of sheared-flow-stabilized (SFS) Z-pinch devices directly face the core plasma and supply the pinch current. The high temperature, high density plasma environment produces intense particle and heat fluxes, leading to concerns of electrode erosion that limit durability and contaminate the plasma. An improved understanding of these plasma-electrode interactions is required, especially at the high temperatures and current densities required for fusion applications. An experimental investigation is conducted on the ZaP-HD SFS Z-pinch device, which produces plasma temperatures up to 1 keV, densities of 10^{23} m^{−3}, and drives pinch currents up to 150 kA. In-situ measurements of the gross carbon erosion flux from the graphite electrode are obtained with S/XB…

Professor Hermanson talks about his Blue Angels flight
Join us on Thursday November 6 at 3:30 PM for a talk with the G.O.A.T of the Aero/Astro department, Dr. Jim Hermanson. He will be talking about his recent flight with the Blue Angels and his visit aboard the USS Theodore Roosevelt and USS San Francisco (a nuclear attack submarine). Please fill out the Google Form to submit any and all questions you have for Dr. Hermanson. Our fellow aero colleague, Hugh Suratgar, will be moderating this conversation.
