Re: Power supply.

If you don't know what a transformer core is, you should do a lot of studying before you even think about powering up an x-ray transformer. It's for your own safety as well as those around you that you learn the fundamentals before working with such dangerous things.

Re: Power supply.

That looks like a wound bobbin with no core, relatively useless unless you can find an appropriate core to put into it.

Re: electric isolation of the feed through on the vacuum side

<t>I wouldn't worry about hitting the knife edge, there's far too much metal closer to the inside. Anyways, a fusor doesn't have enough stored energy to cause substantial surface damage (or at least it shouldn't if you're being safe).<br/> <br/> The usual fault is an arc drilling a hole through the ...

Re: electric isolation of the feed through on the vacuum side

<t>A number of people have had feedthroughs destroyed by internal arc-throughs. Usually it doesn't happen for quite a bit of run-time though. Just about anything will work for a short period of time. What's harder is getting a setup that will work for hundreds of hours of runtime. <br/> <br/> Some a...

Re: Finding the Right Transformer for Fusion!

Any reason why not? Pretty sure you can, as far as I know a VFD is just an inverter which you can certainly run a transformer off of. If you were going to DIY the circuit, you would just build an inverter anyways without any motor control systems.

Re: Electrolysis of Heavy water - Drying the deuterium gas

<t>I have passed it through a drierite column, which did alright. I also passed it through a copper tube coil that was in a bath of ice water, which seemed to do even better. Ideally, it would be much colder than ice water.<br/> <br/> My first neutrons were by electrolysis, although I didn't get ver...

Re: Flyback Transformer

<t>Building your own is all that easy (although it's not trivial either). It doesn't take much electrical knowledge, just some craft in insulating everything. You can order cores very cheap from TSC international.<br/> <br/> As for amazing1, they are a legitimate company and will send you what you o...

Re: Diff pump

<t>That's an awful lot of money for a turbo pump on ebay. They frequently come up for under $100 without a controller, which could be purchased separately or pretty easily made yourself if you know anything about electronics. In fact I'm pretty sure there are some <$100 turbos up right now, someone ...

Re: Diff pump

<t>A lot of turbo's take forever to turn off, making DP's just as good from a speed perspective. My little NW50 air cooled DP turns off about twice as fast as the little 4.5" turbos I use at work (which clearly don't have magnetic braking). With very careful gas bleeding that can be accelerated to a...

Re: Flyback Transformer

<t>It looks like they're doing ZVS on that amazing1 driver. That could also work, I've always personally preferred ZCS.<br/> <br/> The multiplier is using 40kv capacitors with 5 in series (5 multiplier steps) making it effectively a 200kv capacitor, and the diodes are 64kv*5 with respect to the full...
