History of Focus Fusion
Jul 20, 2006With an emphasis on the Dense Plasma Focus.
Dense Plasma Focus ("DPF")
Invented in 1964, the Dense Plasma Focus ("DPF") is known to generate fusion reactions. The question is: can it generate net energy from fusion? LPP's DPF is designed to test this idea with pB11 fuel.
As a proof of concept device, many things had to be taken into consideration for its unique design.

LPP's Dense Plasma Focus Design
Electrodes:
The heart of the device. As the powerful current passes over these electrodes, a plasmoid will form, fusion will occur. Will it be enough for net energy?

DPF: History, applications, other projects
DPF projects worldwide
Coming soon, a catalog of other DPF projects, and where LPP's DPF fits (not too big, like Warsaw and Vegas, not too small like the typical model. A Goldilocks machine.)

DPF Applications:
The DPF is a pulsed X-ray and neutron source (if running with deuterium) for medical and security inspection applications and materials modification. For next-generation microelectronics lithography, surface micromachining. Also testing electronic equipment and detecting nuclear materials.

Singapore DPF group demonstrates high efficiency
Jan 03, 2005A research group in Singapore, using electrodes quite similar to those proposed for the next set of focus fusion experiments, have demonstrated efficiency of energy transfer into plasmoid of at least 50%.
Conclusions from anode design study
Feb 03, 2004We have competed preliminary anode design studies. These indicate that for copper, stress limits will not be exceeded as long as current at the base of the electrode does not exceed 0.75MA per cm of anode radius. Interestingly enough, this is exactly the same as the “rule of thumb” limit, based on experimental experience, that was previously formulated by Bruce Freeman of Texas AM.

Pan American Dense Plasma Focus Network - Discussion
Jun 20, 2003In May 2003, Jorge Pouzo, a leading plasma focus researcher at the University of Buenos Aires, Argentina, initiated a discussion among DPF (dense plasma focus) scientists in North and South America aimed at forming a “Pan Americana DPF Club”, an organization of DPF researchers. The result has been the formation of an ongoing network for communication among the researchers, which has already produced valuable discussion and will lead to closer collaboration.
