The dense plasma focus (DPF) is one of the most efficient sources of fusion reactions for a given energy input. For smaller DPFs, fusion output scales as I4 or faster, where I is peak current. However, energy output in high-current machines saturates at 1012 reactions with deuterium as fill gas. To attempt to overcome this saturation, experiments at the focus fusion-1 (FF-1) facility have tested the use of smaller-radius electrodes (2.8 cm radius anode) and higher fill-gas densities > 30 T.
