[edit] Scaling
The article states that the energy density, temperature, and electron density are essentially constant for machines which vary by three orders of magnitude in total energy. What are the typical values for these three parameters. How does the plasma beta vary? --Art Carlson 12:08, 31 July 2006 (UTC)
[edit] Plasma Gun
A plasma gun is similar to a Plasma Focus, but not the same. The configuration of the electrodes is entirely different. Moreover there is no pinch in plasma guns. The aim of plasma guns is simply to spit out, in a given ambient with proper pressure, plasma jets, not to pinch them.
- I've qualified the difference, is that OK? --Iantresman 20:43, 8 July 2007 (UTC)
[edit] Video removed
The link to a Google TechTalks video explaining operation of DPF and its possible use for power generations was removed. Why? TristanDC (talk) 09:07, 31 May 2008 (UTC)
[edit] New scheme of DPF
Further to a request on the French graphic Lab, I recently created this image showing the functioning of the DPF, which is labelled and uploaded on Commons, thus everyone can use it. Karta24 (talk) 08:53, 24 August 2008 (UTC)
[edit] Focus Fusion-1 achieves first pinch
The baby is born! After seven years of theoretical work and raising money, five months of design, five months of construction and assembly, and a week of testing, LPP now has a functioning dense plasma focus, Focus-Fusion-1. The first shot, using helium as the fill gas, was achieved at 5:29 PM today, Oct.15, and the first pinch was achieved at 6:04 PM on the second shot. The fact that a pinch was achieved so soon was evidence of the soundness of the design.

- hmm, it seems i was a bit late to the game. i should have figured - after all, this IS wikipedia. :) Kevin Baastalk 14:28, 19 October 2009 (UTC)
[edit] Perspective Application
I wonder why none mentions another perspective application - a hybrid fusion-fission reactor? Fusion could supply the neutrons, and burn the sub-critical fission waste. —Preceding unsigned comment added by 82.102.87.135 (talk) 04:24, 26 January 2010 (UTC)
[edit] Description is difficult to understand
I understand the operational description between points 1 and 3. However, point 4, which isn't actually mentioned, is confusing. It appears that the plasma "sticks" to the top of the anode while the larger sheath on the cathode side keeps moving. This causes a cusp to form at the top of the anode, which pinches. This seems to be what the (excellent) illustration here on this page is showing.
Is this a correct description? If so, I'd like to edit the article.
