Linear IEC Device
Posted: Tue May 23, 2017 12:29 am
Hey everyone, my name is Brehnden Daly and this is my first (technically second if you count the introduce yourself post) post here on fusor.net! So go easy on me!
I created what I call a linear IEC device. It is similar to a fusor in that it accelerate ions toward a negative electrode, except it does this in a linear way rather than a spherical way. My idea with this is that theoretically I could eliminate ion-electrode collision by adding a strong-enough magnetic field running alone the axis of acceleration. I have not added the magnets yet in order to better show the design of the device. I added an image of the device titled "prototypeV2device.PNG" to this post. That image shows the full device. This is my first post so I do not know what it will look like, but I can edit the post later if I find there is a better way to add images. It is important to note that the center negative electrode is a washer. Therefore, ions can travel through to the left side and right side.
The device is powered by a cheap little < 40kV boost converter. I do not know the exact voltage, I just know that it is less than 40kV because I connected a 40kV capacitor to try to smooth the output and it didn't blow. Don't try that at home. I am working on getting a better power source, but it's tough to find a good NST these days. I have tried two modern NST's but they seem to blow their fuses soon after I connect the bridge rectifier. Since I am using a boost converter, obviously the amperage is insanely low and the DC is pulsed.
Here is a link to a video of the device: https://youtu.be/RirTCLZqBUY
My plan is to add some permanent ring magnets around the tube near the center negative electrode. My theory is that this will add a pinch effect preventing the plasma from following the electric field and colliding with the negative electrode.
You can see in the video that the plasma density is more on one side and less on the other side. I believe this is due to tiny inequalities in the length of the left and right polycarbonate tubes. This is also probably due to high pressure. I have a cheap Harbor Freight vacuum pump.
It is also clear in the video and other attached images that the plasma rapidly turns white from its purple-blue color. This is probably due to contaminants in the chamber. I didn't really clean the tube after cutting it/sanding it. I also epoxied the negative electrode to the two polycarbonate tubes. So the plasma could be burning this adding some unknown gas into the chamber. The chamber is originally just filled with air. I am a broke college student, so everything was created on a budget.
I am posting this to get some feedback. Has anyone created a device like this? If you have, how far did you go with it? What did you find? I'd also like to know if there is anyone else in the Orlando area.
And if nobody has created it, I'd still like to see some feedback as I definitely do not know as much as many of you!
And, to conclude, thank you for spending the time to read this!
