Speaker: Dick Majeski, Princeton Plasma Physics Lab
Title: "You take the high road and I’ll take the low (recycling) road to fusion
- LTX – β and the route to a better tokamak"
Abstract: Improved plasma confinement is the single most impactful factor affecting the size and cost of an eventual fusion reactor core. Low recycling walls have long been known to improve confinement in tokamaks, although they have yet to be tested in other confinement approaches such as stellarators. We briefly discuss the impact of confinement on reactor scale, and the impact of reduced recycling on confinement. We will discuss results from LTX and LTX-beta, and how they inform the low recycling approach to fusion. Finally, we will discuss future research directions in low recycling confinement.
Bio: Dick Majeski is a principal research physicist and head of the Lithium Tokamak Experiment (LTX), a device that allows scientists to study the effect of the liquid metal on fusion reactions. He is an expert in tokamaks and walls for fusion devices, especially those coated in lithium. He earned his bachelor's and master's degrees from the University of Scranton and his PhD in physics from Dartmouth College and is a Fellow of the American Physical Society.
