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)
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.
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)
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)
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.

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)
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.

The first paragraph past the introduction reads like a patent application with missing figures:
A charged bank of electrical capacitors is switched onto the anode. The gas within the reaction chamber breaks down and a rapidly rising electric current flows across the backwall electrical insulator, axisymmetrically, as depicted by the path (labeled 1) as shown in Fig. 1. The axisymmetric sheath of plasma current lifts off the insulator due to the interaction of the current with its own magnetic field (Lorentz force). The plasma sheath is accelerated axially, to position 2, and then to position 3, ending the axial phase of the device.
I don't see any figures when I view the page in my browser. I assume this was blindly copied.
