Glad to have you with us, theanphibian.

A simplified view of the DPF is the Lee model, developed by professor Sing Lee of the UN University. http://www.nsse.nie.edu.sg/research/plasmaphysics/ComputationPkg.htm will get you the Mather style DPF simulator and all of the math behind the simulator, which includes the physics. This model divides each machine cycle into 5 phases, the Axial, Radial inward shock, Reflected radial shock, compressive/radiative, and expansion. As the names imply, the last 4 phases use a cylindrical model.

My understanding of the purple image is that its the filaments beginning to kink up near the beginning of Phase 2. I still don’t have a direct correlation between much of the Lee model (simplified but easier to grasp initially) and the LPP model, which is very detailed. But there are 2 simulators being tested. Maybe FF will have a package similar to the Lee model this year.

The compressing cylinder is the collapsing magnetic field, which can exceed 10GG, heating the plasmoid containing the fuel for any shot by compressing it into a near solid. The plasmoid diameter for the energy yield charts is 8.6 microns. As the plasmoid is compressed, some fusion begins, producing positively charged helium ions and the resulting free electrons. The magnetic field provides the motion and the tight focus of the beams.

Even though it needs to be shown as a beam for that concept, the electron beam is actually busy heating the plasma even hotter. Something like thermal runaway in an overheating transistor. This is where the majority of the fusion reactions begin occurring.

I’d love to give presentations on the FF in the Great Lakes region, but PM me if you can provide a venue in other regions and we may be able to swing at least a tele-conference. I’m currently working up a plan to clone the FF-1 at over 2,000 universities and colleges to pull a time warp on public awareness, time to peer-review, time to market, etc. I just posted the rough outline on our facebook wall, if you’d like to comment.

I think it was Napolean Hill in Think and Grow Rich, that thoughts draw others of their type.
