Re: My progress II

Hello Mr. Rowley, Thank you very much for your suggestions. I will work on flashover protection. About the grid, this shape was easier for me to build, we used stainless steel wires and I couldn't make a good spherical grid. I will try again and see if I can get a different shape. Regards, Eduardo

Re: My progress II

Hello, I would like to update you about my fusor project. I stoped to work on the fusor for a while, because I needed to focus in my studies. But now, here I am again. Today we tested some parts of the system. We have put the system under low pressure (1x10-5 torr),and we have made some plasma (arou...

Re: My progress II

Hello Mr. Brown, Thank you for your advises. About the school presentation, I was thinking to use my fusor more like a display and show some videos about it, but I haven't set up this presentation yet. Mr. Allers, Thank you for your post. I am learning a lot about fusion and improving my english. I ...

Re: My progress II

Hello Mr Brown, Thank you for your advise. I used the Barrier Calculator from University of Toronto ( https://ehs.utoronto.ca/our-services/x-ray-safety/x-ray-barrier-calculator/ ) and got a 0.83 mm thickness, but we are planning to use 1.0 mm and in some parts 2.0 mm. My father will work with the le...

Re: My progress II

Hello, I have been working on my Fusor (it was named Kelvin II) and I have a lot of improvements. It is almost complete to produce neutros. I would like to share my progress in my neutron detector. I change some emails with Mr. Bob Higgins and I am using his paper ( http://www.fusor.net/board/viewto...

Re: My progress II

Hello Mr. Brown,

Thank you for your suggestions. I am using a turbo pump. I believe one of my gaskets isn't very good, I will change it and heat all the chamber to see what happens.

Regards,

Eduardo

Re: My progress II

Hello, Thank you for help. The lowest pressure was 4.2E-4 torr. We measured the increase, and in one minute it increased from 10 to 20 militorr. Is it good? In my next try I will get more precise measurements and try to get plasma during 30 minuetes to clean the chamber. Do you think a smaller grid ...
