Fusor Forums

<t>Good call on the low energy electrons--they are! Your numbers are off by a factor of 10 though (4 eV and 8 eV wouldn't even Ionize a gas!). So I have a range of 40 eV to 80 eV electrons. The temperatures indicated are produced at a voltage of ~-1000V and a pressure of 165 mTorr. They probably loo...

<r>Last year I was able to make a fusor for my senior project for a completion of a physics degree. I also constructed a triple Langmuir probe, which was able to make near instantaneous and repeatable measurements of electron temperature. The process is semi-documented here: <URL url="http://www.fus...

<t>Brian,<br/> <br/> Post those papers if you don't mind. <br/> <br/> As with the 'another 50 years joke', not only do we need a gifted set of engineers to design a viable reactor and make break even but also a group of politically aware and gregarious scientists that can get the required money toge...

<t>Just pointing this out, as I was about to hop in this bandwagon.<br/> <br/> "DISCLAIMER:<br/> Please note that the materials we use for manufacturing the models make the models suitable for decorative purposes and they are not suited for any other purpose. The models are not suitable as toys to b...

<t>Finally have time to give explanations/comments.<br/> <br/> Chris: I need to move the probe around more and take more measurements and see if I get the same distribution. The hard part is the data measurement for these operations is tedious and we have not had the time to do it. The fusor needs t...

<t>My formal senior thesis on the Fusor. Still not complete, I have a summer <br/> of research to do with it. Includes topics such as:<br/> <br/> Introduction to Fusors<br/> What is Plasma?<br/> Constructing a Fusor<br/> Measurement<br/> Operation<br/> Experimentation<br/> <br/> You all have helped ...

<t>So here it is. The grand finale of my project, there should be more data coming, but its the best yet. I posted this a week ago, but I've been busy with graduation and finals.<br/> <br/> I managed to stick my Langmuir probe directly inside of the electron beam in jet mode. I then kept the pressur...

I will have a bigger post on this later. I'm writing my senior thesis right now. Best data yet. I'll let you have your opinions.
Yes, it is repeatable.

Center probing. I'll tell you guys how it goes in a few days.
We're in the process of taking our finals.
