I want to expand on that thought a little more.
1. The oscillating energy is lost as heat in the electrical equipment of the device and the Faraday cage of the room. Stopping that loss would keep things cooler.
2. Capturing the oscillating energy to partially recharge the capacitors would improve the energy input-output ratio.

I think this will become a design consideration in production machines or high repetition rate experimental machines. It would be good to start collecting ideas on how to address this problem.

I am under the impression that the current is sloshing back and forth from the pinch area to the capacitors. If a detector coil is placed close to the cables connected to the capacitors it could determine if the current is oscillating back and forth at the same frequency as the voltage readings on the oscilloscope.

You may want to look at 1½% lanthanated tungsten for longer life in the pre-ionization electrodes.

Van Roessel wrote programs to analyze the oscillations, concluding that they were due to current sloshing back and forth along the transmission plates that connect the capacitors to the electrodes.

A detector coil should pick up the oscillating magnetic field associated with the sloshing current.

I assume the parameters will be related to the interelectrode potential and the magnetic flux of the field. ( I tried to write some extremely rough draft equation but the forum does not appear to use MathJax.)

Look for posts by asymmetric_implosion on this website. He is an expert in the information that you are looking for. He has participated in a lot of the technical discussions.

There is no typical DPF device. They range in size from small tabletop units for training college physics students to very large machines for research purposes. So far no one has indicated that they have produced more power than they have used to operate their device.

If you are strapped for cash at this point then I’m concerned that you may take other shortcuts. This will not be cheap unles you have access to good salvage equipment. A functioning unit can produce radio frequency interference and some x-rays and you need to take precautions.
Copper is used because it is an excellent conductor of electricity and heat. It has a reasonably low level of corrosion. You can make a demonstrator unit using iron parts but the metal needs to be shiny bright and iron tends to rust easily. Your power supply will be the most expensive part and it needs to supply a large enough current at high voltage to give you a satisfactory demonstration. The dimensions and gas pressure are important elements too as has been explained in other posts.

I would like the ability to post links that don’t break because the forum doesn’t understand some links from other websites.

Can you provide an example or a more detailed description?

Quoted from another post:

Francisl wrote: I was looking at Wikipedia and saw a list called Category:Environmental organizations based in the United States. Some of those organizations may look favorably upon this fund raising campaign. There is a group called Ceres. One of its key accomplishments is that it Founded and directs the Investor Network on Climate Risk (INCR), a group of 100 leading institutional investors with collective assets of more than US$10 trillion. Its members include Deutsche Asset Management, State Street Global Advisors, and TIAA-CREF, as well as the pension funds of California, Florida, and New York.
Some of the groups on this list may help with a Kickstarter campaign and some may oppose it. I don’t know enough about them to tell the difference.

The above links aren’t working very well today so you can copy and past the following links: http://en.wikipedia.org/wiki/Category:Environmental_organizations_based_in_the_United_States

Edit by zapkitty: Links fixed.

zapkitty, thank you for fixing the links.
The link for Ceres should be “http://en.wikipedia.org/wiki/Ceres_(organization)” . The forum software seems to change it to “http://en.wikipedia.org/wiki/Ceres_organization” . The parentheses are getting dropped for some reason, resulting in a bad link.

This article on plasma railgun will answer some of your questions.

[Francisl]

zapkitty, I agree with your proposal.

I’m nowhere near the physicist it would take to even know if Rayleigh-Taylor instabilities even affect FocusFusion. All I know is that both experiments are Z-pinch based. Is there any applicability of this info on FoFu-1?

Please consider two points:
1. This demonstrates that progress and innovation are occurring in the fusion field.
2. LPPx showed the effectiveness of a small axial magnetic field to improve the intensity of a pinch. This is similar.
