Electromagnetic Theory: Static Fields and Their Mapping
I recently received a copy of Electromagnetic Theory: Static Fields and Their Mapping, in the mail. It's a dover math book and as a result was quite cheap. The book is quite old but is one of the few sources on modelling 3d electric potentials that I've been able to find. The math is quite heavy, but offers the hope of an analytic solution to the electric field generated by the rings and cylinders many fusioneers use in their devices. Hopefully it is of interest to some on the forum. The book is by Ernst Weber.

Re: Electromagnetic Theory: Static Fields and Their Mapping
Interesting and thanks for the reference. I am currently writing a small but hopefully sufficient, (for the noobie), an understanding of what is going on in the fusor and why it works and doesn't. A contrary statement, but how true it is. Understanding what goes on in the simple, medium size, spherical fusor is complex to say the least. One would think being a DC device that is effectively a glow lamp brought to near breakdown, that the fields, once established, and stable operation is obtained that the resultant stable fusion numbers resulting are fixed. This is probably exactly correct, however there are many modalities that create the whole of that fusion. What are they? Which ones predominate? In what region? Fields are one thing that can be fully established. Fusion is and always will be a probabilistic crap shoot in a torrent of energetic particles, not within an electromagnetic field, but a static electrical field of potential energy that establishes only a gradient or even multiple gradients. Any current supplied to the device is the driver of the creation, (ionization of particles), to hopefully create a deuteron current. The supplied current from a supply is distributed over billions of deuteron charge carriers. The potential static field does all the acceleration and thus fusion. Current produces no real magnetic field of significance. (2-20ma) at best over what might be a single turn distributed over all the electrons and ions zipping around in the device. Lets just talk about static fields. Currents create useful deuteron numbers within the fuel in the device.

Fusion is the energy of the future....and it always will be
The more complex the idea put forward by the poor amateur, the more likely it will never see embodiment

For those that just want to get an idea about the voltage breakdown caracteristics of the feedthrough and related high voltage junctions, there is a little program called INCA.
You can find it on this page:
http://www.coe.ufrj.br/~acmq/programs/
Although its face purpose is to calculate mutual inductances in air cored coils, it also has a section where it calculates, and plots, the field around balls, toroids, or whichever solid you want to investigate.
It is a small executable, and every high voltage enthusiast should have it.
A google search about breakdown voltage of toroids, gave this link:

Where the author of the program gives an introduction of it's capabilities.
