Researchers at PPPL have just finished work on an upgrade of the Lithium Tokamak Experiment-Beta device. The upgraded device uses a new unique lithium coated interior. This device was reportedly the first to keep the internal temperature consistent from the hot core to the cool edge of the walls. The lithium is there to absorb the stray plasma and cool it down before it reaches the walls of the tokamak and causing damage or unpredictable interactions. They were able to increase the beam power from 500 kilowatts to 600 kilowatts which increased the heating power by a factor of ten.
