Plasma club submission

Post by Dominick Quaye »

Over the past few months, I (Dominick Yatte Quaye) and 2 friends (Javier Blanco & Calvin Holms) built a Demo fusor. Pictures of the plasma and the general setup are attached.
High Voltage: Our HV system consists of a variable water resistor (for current control), A variac, and then an MOT feeding into a full bridge rectifier made from microwave oven diodes.
Vacuum setup: A Welch 8920A that I fully disassembled and refurbished after getting it off eBay for 200$ in terrible condition. It is connected directly to the chamber with a plastic hose. The vacuum gauge is a VG64 digital gauge with a 0.5 micron resolution. Even with the huge leak our chamber has right now, the pump consistently gets the pressure down to 50 microns. (It's 7cfm so it kinda out-pumps the leak)
Chamber: Made of 5 inch ID stainless steel tubing with 3 outlets of 3/4in OD stainless tubing welded on. (third is sealed off right now but will hopefully allow for us to inject D2 later on)
The plasma in the pictures was created at 2.1kV and a pressure (ranging from picture to picture) of 55-300 microns.
We intend to turn this into a real fusor soon to create various Isotopes and play around with the plasma using a magnetron. We are currently refurbishing a diffusion pump, fixing our chamber leak, and building a D2 setup to combine small amounts of heavy water and sodium to create D2 and Sodium Deuteroxide. We have yet to start on the HV system and necessary chamber changes.

Thanks :)

Great work! I will add your names as a team effort to the plasma club listing. All the best as your work advances.
