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


DPF assembly:
The bulk of the device exists to deliver a powerful current to the electrodes.
Electrode Assembly
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
DPF Animation
To help visualize the theories being tested by LPP with this device.

LPP's Experimental Space Design

DPF floor plan
Floor Plan
The DPF is in a room with three foot thick walls. Note the maze-like entrance.
Mini Faraday cage
Shielding:
To keep the RFP from disrupting instruments.
Unistrut
Support structure
To elevate the parts of the machine so that researchers can get "under the hood"
Front Plate
Instrument interface
To connect diagnostic instruments to the experimental device.
Time of Flight
Instruments
Otherwise how will we know if we got enough fusion?

DPF: History, applications, other projects

microfocus
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.

History:
The DPF was invented in 1964 by Mather and Fillipov.

New 3D Fusion Poster

Apr 14, 2011

A big Thank You to Sascha Becher aka Stereotron for producing this stereoscopic 3D poster of the electrodes of the Dense Plasma Focus

Please feel free to download and print copies of this poster for your pro-fusion events. Also, feel free to design more posters, collages, fine art, mixed media extravaganzas.  As we did with Stereotron, we are happy to supply you with the full sized raw images for manipulation.

Morphing towards a fusion future

Jan 29, 2011

We’ve used these two images - One from the LPP lab and one by Torulf Greek - side by side to represent how we want fusion to progress, so why not up the ante with some morphing action?


Switches and Sparkplugs

Jan 01, 2011

This post breaks down the design of FoFu-1’s twelve spark gap switches, which release current from the twelve capacitors to the main electrodes.  The switch plates and spark plugs are undergoing “ruggedization” to overcome the challenges discussed here.


FoFu-1 Design

Seasons greetings everyone!  I’ve just uploaded a set of photos on FoFu-1’s design.  This set is packed with explanations and information.  Let me know if it gives you a sense of how the machine fits together.
