National Security Technologies had built in 2008 a 500 kiloJoule Dense Plasma Focus called Tallboy that produced 3 MA (million amps) of peak current and is now testing a 1 MJ (million joules) Dense Plasma Focus that is expected to generate over 4 MA (million amps) of peak current, which will make it the most powerful in North America, and possibly in the world. The work, while unclassified, was funded by a Department of Energy National Strategic Security program that had previously limited public disclosures. Tallboy achieved a maximum neutron yield of 6x10^11 with deuterium, when charged with 250 kJ. Currently the new 1 MJ Gemini machine uses electrodes with the following dimensions: anode radius 7.5 cm, cathode radius 10 cm, insulator length 7.5 cm and electrode length 50 cm, which makes it intermediate in size between the larger PF-1000 in Warsaw and Focus-Fusion-1 in New Jersey.
The NST work is related the efforts of Lawrenceville Plasma Physics (LPP). LPP is looking to develop dense plasma focus fusion (focus fusion). LPP has $1.2 million in funding. Lawrenceville Plasma Physics, the group looking to develop dense plasma focus fusion (focus fusion), has provided details of $1.2 million in funding and the project plan.
