context_page_description: The Lithium Tokamak Experiment, and its predecessor, the Current Drive Experiment-Upgrade, are devices dedicated to the study of liquid lithium as a plasma-facing component at Princeton Plasma Physics Laboratory.
context_section_description: Operated at PPPL from 2000 to 2005.
  As the first test of large area liquid lithium PFC, CDX-U had a toroidal tray on the bottom of the vacuum chamber to contain the lithium. Even with this partial non-recycling PFC, major improvements in plasma performance were obtained. Impurities were reduced, and a dramatic improvement (x6) in energy confinement was observed in 2005.
