Fusor's going great

It's been about a year since I moved in to my new lab at the Burlington Nuclear Engineering facility at North Carolina State University. My vacuum system reached a new ultimate pressure today of 1E-7 torr My vacuum system is fully functional and I have: Two large Helium 3 tubes 3 L Deuterium gas A m...

Re: Mini-five minute fusor

I should be getting a diode today so I should be able to rectify my power supply from AC to pulsed DC. If I do get confinement then would this fusor be smaller than Rowley's?

Re: Mini-five minute fusor

I'm not sure about a pressure controller but I do have a controller for my varian 524 ion gauge hhead. I replaced the electrical pnuematic gate in the lower picture with a hand cranked gate.

Re: Mini-five minute fusor

<t>I'm already in the plasma club Richard, I'm conducting research with my large fusor at NC State. I'm just using this smaller fusor as a spectrometer source since I want to monitor plasma coloration and plasma purveyance at different voltages. In my new lab I have a new roughing pump, an turbo pum...

Mini-five minute fusor

<r>I was inspired by Mark Rowley's five minute fusor and I decided to make one myself. I was able to cut a two inch long piece of one inch diameter borsillicate glass that was .18 inches thick. I used a sparkplug as a feedthrough. I used npt piping and an alcatel 2008 pump as my roughing pump. What ...

High power voltage quadrupler

<t>I am considering making a voltage quadrupler for my fusor. Does anyone have any schematics of any voltage multipliers they built? My power supply is capable of 14,400 volts at 480 mA. Will microwave diodes and capacitors suffice or do I need diodes and caps that are rated at a higher wattage? My ...

Diffusion pump grounding

<t>I am replacing the 30 year old heater wire in my diffusion pump with new heater wire that I ordered online. Where does the grounding wire go in a diffusion pump? Is it grounded to the pumps metal body? If not where does the grounding wire go? Also I can anyone identify if my diffusion pump is a v...
