Transparent Ceramic Viewports

After reading Liam David's recent thread about damage to glass viewports I was curious if anyone had any success with other materials. I know many fusioneers have had success with using ceramics on their high voltage feedthrough. Has anyone attempted to use transparent ceramics such as perlucor or t...

Re: Vacuum Chamber Construction

Yes, I'm copying Andrew Seltzmann's design that he's posted on his website. I doubt my machining tolerances are as good as his though, I've been using an edge finder and tilting table instead of the precision rod and indexing head setup he used. I've got a single half nipple CF port you can see part...

Re: Vacuum Chamber Construction

Machining has been completed on one hemisphere and the angled ports have been started on the second hemisphere.

Re: Vacuum Chamber Construction

After a school enforced break, I've managed to pass all my classes for the semester and have found some time to work a bit more on the machining of the hemispheres. I've successfully completed a second angled port on one hemisphere. What took me most of summer to finish with interruptions and mistak...

Re: Python Simulation

Here you go! The code uses numpy and matplotlib, two freely available python packages. A matrix called fusor is defined and a finite difference approximation is performed until the matrix converges on a solution. The program is based on some matlab code I found on a professor's website , he has writ...

Re: Python Simulation

Hi Harald,

Definitely not planning to publish anything, but happy to share the code I have so far, it's not very complicated at all. How would you like me to send the file?

Re: Python Simulation

I'm aware it won't be an accurate representation of a spherical system, but it seemed a good way to get my feet wet seeing as this is the first time I've written a numerical simulation. In particular I was inspired by the following work done by a physicist by the name of Matt Lilley , who used a 2d ...

Python Simulation

I've decided to break out the work I'm doing into its own thread. As of right now I've completed porting my initial code over to python, which means that I have a 2d representation of the electric potential in a fusor. My next step is to get a simple particle in cell simulation going with a small nu...

Re: Fusor Computer Modeling - Call for Contributions

In my limited spare time at school I've been working on modelling a fusor numerically. Since I'm unable to work on the construction of the physical device while at school (all of my components are in my hometown), I've been trying to apply what I'm learning in my numerical methods class. At this poi...

Re: Maybe someone can help?

As a relative newbie, and learner on the forum I'd like to add my two cents and say that strict enforcement of the rules really does improve the forums. I know every post I click on will have useful information for me, the discussions are worthwhile, and I always learn something. I spent a lot of ti...
