First Operation of LTX-β

POSTER

Abstract

LTX-β, the upgrade to the Lithium Tokamak Experiment, approximately doubles the maximum toroidal field (to 3.4 kG), plasma current (to 150 – 175 kA), and discharge duration (to ~100 msec) while retaining the same plasma geometry, and the heated high-Z liner featured in LTX. Neutral beam injection (NBI) at 20 kV, 35 A provides auxiliary heating, core fueling, and momentum injection, with an injector provided by Tri-Alpha Energy. New lithium evaporation sources allow between-shots recoating of the walls. Upgrades to the diagnostic set strengthen the research program in the critical areas of equilibrium, core transport, scrape-off layer physics, and plasma-material interactions. Here we will discuss first results from LTX-β, as well as the research goals.
