The Lithium Tokamak Experiment (LTX) was a tokamak located at PPPL that was constructed as an upgrade of CDX-U. It was the first device to have a full liquid lithium wall and was used to study lithium as a plasma facing material. LTX had a toroidal field of 0.17 T and reached a plasma current around the 100 kA. It had a major radius of 40 cm and an aspect ratio of 1.6. In 2016, LTX ended operations to be upgraded to LTX-β.
