asymmetric_implosionSorry for the terribly slow reply. I wish I could say I meant the spelling but I R an engineer. 🙂
The papers are listed below.
Ion beam reconstruction from neutron time of flight:

Optical framing (This is one of my favorite papers with images)
Jos´e Moreno, Patricio Silva and Leopoldo Soto. “Optical observations of the plasma motion in a fast plasma focus operating at 50 J” Plasma Sources Sci. Technol. 12 (2003) 39–45
This short list has references to other diagnostics people have tried. The list can be very extensive. If you really want the best pulsed power diagnostics suite at the moment, you need to look at the Z-diagnostics. The NIF diagnostics are coming along quickly. They are focused on a more difficult problem but they are progressing by leaps and bounds every year.
The FoFu approach….If one is to produce GigaGauss fields something has to happen that does not happen in a conventional plasma focus geometry. The filaments could be key to the FoFu approach. The measurements of magnetic fields in the pinch geometry is challenging but I do know a technique that is being developed base upon the deflection of a high energy proton beam passing through the pinch. I don’t know if the spatial resolution will be enough for the plasmoid but time will tell. I’ll be honest, I am very skeptical. Time will tell.
Glad to hear $50K is not too big in your mind. I think the materials testing could be taken a long way with $50K.
