AC to DC conversion for electromagnet
AC to DC conversion for electromagnet
(OP)
I am looking to make a home-made crude linear particle accelerator. I have already begun the work of assembling the electromagnets and the vacuum system, but Im finding that a power source is quite difficult to come by. I need to convert normal 120 VAC wall current, into 10,000 VDC to power the electromagnets. I was wondering what would be the cheapest way to accomplish this.

I'm only familiar with ion implanters, but, there are some similarities, I think:
> A gas is ionized with a 25kV extraction supply
> The ionized gas is run through a mass spectrometer to extract the desired species
> The electrostatic accelerator (up to 200kV) accelerates the ions into the target.
If 10kV is the highest voltage, it doesn't seem like you have enough kick to get much more than tickling CRT phosphors.

10 KV for electromagnets? Electromagnets usually have low voltage and lots of current. Wire wound around a core to make an electromagnet needs isolation between each winding and connecting a coil with a few ohms of resistance to a 10KV supply would make a good fuse blowing machine.
Anyway, just in case I misunderstand what you're doing:
A Cockcroft-Walton circuit (Check the internet) is a good way to multiply DC voltages. It uses capacitor and diodes and you can keep adding steps to go higher and higher.
I'd be interested to hear more on your project.
Thanks
