The Lithium Tokamak eXperiment (LTX) allows for the study of the application of lithium to a tokamak wall and lithium's effect on plasma temperatures in both spherical and conventional tokamak models. The upgrade would include a 700 kilowatt neutral beam on loan from Tri-Alpha Energy for fueling, diagnostics, and heating. An upgraded toroidal field power supply would increase the toroidal field from 1.7 kG to 3.2 kG and the plasma current from 80 kA to 150 kA and an expanded Ohmic power supply would provide longer discharges at improved plasma current.
