Dense Plasma Focus / Plasma Gun (Diagram)

You might inquire with http://www.focusfusion.org and/or http://www.lawrencevilleplasmaphysics.com/. Alternately, for a similar but possibly slightly different approach / company, try http://www.electronpowersystems.com/.

A couple papers from the focus fusion site:

http://arxiv.org/ftp/arxiv/papers/0710/0710.3149.pdf
http://arxiv.org/ftp/physics/papers/0401/0401126.pdf
http://www.physicsessays.com/doc/s2005/Lerner_Transparencies.pdf

A few from the EPS site as well:

http://techreports.larc.nasa.gov/ltrs/PDF/2000/cr/NASA-2000-cr210654.pdf (having technical issues loading the report at this time; hopefully it clears up eventually...)
http://www.electronpowersystems.com/Images/Response%20to%20Nasa%20Report.pdf

A page with a brief explanation of the DPF:

The next site has a couple positive notes, but I don't know that it gets into technical specs, etc.

Hope some of the above points in the right direction... You might also try searching http://www.arxiv.org on "dense plasma focus" or "focus fusion"? Not sure what all they've got. Hopefully something good, tho'... Likewise, http://adsabs.harvard.edu may or may not have anything.

Anyway, let me know if that helps... =o]
