Fusor Forums

Thanks Dennis, appreciate the advice. I'm finding it harder than expected to operate the Fusor, haven't achieved a stable plasma at high voltages yet. I don't think I've got a stable deuterium plasma yet, as my D2 flow is too constricted, and I can't seem to throttle my turbo pump enough. The turbo ...

I achieved plasma this weekend, on a run less than a minute long. It followed from wiring up and testing my high voltage line and supply. The high voltage line consists of: a DIY connector for the Matsusada supply RG213 coax 100k, 100W resistor immersed in motor oil grounding lugs/wires Feedthrough ...

It can be a lot of fun and rewarding (and tough!) to learn the theory behind the actual device we build. However, I wouldn't get too caught up in learning theory before actually making something. My Fusor isn't done yet, but one thing I'd do differently would be to get to work with my hands quicker,...

Good catch, thanks John. I've now got the power supply working as far as I can tell - HV status light switches on and off as expected, voltage readout reads 0-10v on my led meter, changing as I turn appropriately connected potentiometer. Progress!

Have been working on getting my 30kv/20ma power supply working. It's a Matsusada unit, all controlled via a fairly simple I/O. Datasheet is attached. My first step has been trying to get the HV status pin to LO, which means HV ON. As far as I can tell from the datasheet, this only requires shorting ...

Quick learner! Welcome David, the FAQs are where you start. Make sure to take a good look in Images Du Jour and any videos of Fusor you can find too - they'll show you how things pan out in reality.

Best of luck.

The first part of your message gave me a shock Richard, relieved to see the caveat for forepumps. My standard procedure when finished pumping and using the system is to first turn off the turbo pump. I leave the mechanical forepump running. After an hour or so I look for a noticeable rise in pressur...

I just finished leak testing my gas line and it’s in place now. Dad and I put together the clamp arrangement that holds the D2 lecture bottle in place. He welded it, as I have next to no welding experience. My next step is to complete my RG58 HV cable, and connect my power supply to ballast resistor...

Nate, the FAQs do provide a good push in the right direction and outline all that you need. Watch videos on Youtube, find links to websites, most of all look in the Images Du Jour to see the parts breakdown and what the systems look like. Get a mentor/guide. You need someone you can meet regularly a...
