Lawrenceville Plasma Physics
Experiments and computer simulations to investigate the capability of DPF for fusion power are underway at Lawrenceville Plasma Physics (LPP) under the direction of Eric Lerner, who explained his "Focus Fusion" approach in a 2007 Google Tech Talk.[25] On November 14, 2008, Lerner received funding for continued research, to test the scientific feasibility of Focus Fusion.[26]

On October 15, 2009, the DPF device "Focus Fusion-1" achieved its first pinch.[27] On January 28, 2011, LPP published initial results including experimental shots with considerably higher fusion yields than the historical DPF trend.[28] In March, 2012, the company announced that it had achieved temperatures of 1.8 billion degrees, beating the old record of 1.1 billion that had survived since 1978.[29][30] In 2016 the company announced that it had achieved a fusion yield of .25 joules.[31] In 2017 the company reduced impurities by mass by 3x and ion numbers by 10x. Fusion yield increased by 50%. Fusion yield doubled compared to other plasma focus devices with the same 60 kJ energy input. In addition, Mean ion energy increased to a record of 240 ± 20 keV for any confined fusion plasma. A deuterium-nitrogen mix and corona-discharge pre-ionization reduced the fusion yield standard deviation by 4x to about 15%.[32]

In 2019, the team conducted a series of experiments replacing tungsten electrodes with beryllium electrodes (termed Focus Fusion 2B). After 44 shots, the electrode formed a much thinner 10 nm oxide layer with correspondingly fewer impurities and less electrode erosion than with tungsten electrodes. Fusion yield reached .1 joule. Yield generally increased and impurities decreased with an increasing number of shots.[33]
