looking for HV power supply with decent current

[Chris Lobo]

Looking to build, as simple as possible and cost effectively, a 100 KV power
supply capable of supplying up to 5 mA current. I'd like it to be able to
handle loads of all types, allow sparking ability, and be able to run free
without connections. An old style induction coil comes to mind, but surely
there are other options and I'd like something a lot smaller.

Thanks,
Chris

Um, that's 500 watts, with all the problems of high voltage supplies.
Sounds like an X-ray power supply, and those ain't small.

"Run free without connections"?

Sorry, that means unloaded and not having damage without a load.

Find a surplus X-ray supply - building something like this will be very difficult and expensive.

Having worked with 60KV 5 mA in the lab, thats not something to take
lightly. About the only wire you can get easily for it is a high grade
RG8 coax. May I ask what you need it for?

Try Gamma High Voltage, in Florida, their price to performance ratio
was very good and their stuff can take a beating.

In another life I worked on similar equipment. Scary stuff.

Something like this?

Expect to shell out $3K or so.

Try 5 Mev irradiation units.

60Kv is nothing. Just a fire cracker.

We like taking the breakers out on the 12kv service lines when things
go wrong

Also, when we get moister inside the vessel at 5 Mv, it does some
nice damage. The DOM's just don't seem to react quick enough to save
the expensive components.

Sounds dangerous on your part.

Do you really need 5ma? would your application
be suitable via a tesla coil?

http://en.wikipedia.org/wiki/Tesla_coil

If you really are looking for a 100KV@5ma's. that's
500 watts. And the next question would be if you need that
in DC/AC ?

DC would be a simpler matter, because you can use a voltage
multiplier
http://en.wikipedia.org/wiki/Voltage_multiplier
http://en.wikipedia.org/wiki/Cockcroft-Walton_generator

Of course, those are on the large scale, but you get the idea.

DC is the simplest to do, you start with a lower voltage of AC
and pass it to a multiplier..

For size, you a frequency that will allow for use of small capacitors
and small xformer.
100KHz or up!.

Cool. If you put your sigfile at the top, the whole post disappears.

Yes, and my newsreader also interprets the sig delimiter properly.

Hope This Helps!

My other toys were 275V 60 amp hot cathode dc arcs, 3 feet long, in
argon and krypton ion lasers. But you can have the 5 MEV.... yikes.

No. RG-8 won't take that. Target is 100 kV not 10 kV. Automotive
ignition leads can handle that for a while. For real, correctly
configured cable see a high voltage vendor, and it will not be cheap.
