About two months ago I started looking for parts and getting ready to build a demo fusor. After some work, we, my team and I, were able to make our demo fusor, which was intended to be used as a science fair project, which was this last weekend and overall it worked very well.
In the video I will link below, you can see how we were able to create a purple plasma, needless to say, this "demo fusor" is not as good as lots I've seen here, but this is just a start and we hope to get better at it and in a few months be able to produce neutrons (I know it will take a lot of redesign). Obviously, this will take a lot of work and research, and I am sure I will find lots of info here.
Some things to note:
·We used a 15kV @ 30mA (rated) NST, we didn't use a voltage meter or current meter, but judging by a consumption chart and what most people say about NSTs, we probably are in the 7kV range or less.
·Our vacuum system wasn't very good, mainly because of our gauge, because we didn't have the funds at the time to get a nice thermocouple gauge, so this is something we will try to improve and hopefully we will be able to give some readings.
·Also is worth noting that in our video the plasma was purple because of possible leaks and not letting the vacuum pump enough time, in our science fair we let it pump for about 5 minutes and instead we got a blue almost white plasma and it was more confined. We will try to record that.
·Talking about our plasma, in our science fair our glass chamber suddenly turned black, possibly because we were producing a lot of heat, so we had to disassemble and clean (which was very difficult) but we managed to do it quickly. After this, we restricted the time our fusor was running.
And that's all! Hope you enjoy and any suggestion/comment/critic would be appreciated.
