Feedthrough where to get
Hello, I am looking for a "cheap" feedthrough with the capacity of 20kV and 20mA, but I can't find any, some of the one's I've seen cost 1000USD and they can go all the way to 100kV and 10Amps, way to much for me. I am far from being experienced with vacuum and fusion itself but I already have some experience on High Voltage. But anyway, I am from Brazil and having some decent machinery here is pretty hard so I can build one. Does anyone know a company that provides feedthrough's at a range price of 250USD? (In brazil that's the Minimum month wage so for me it's already a lot haha)

Re: Feedthrough where to get
Unless you can find one on the used market, a new feedthru will cost you a pretty penny. Patience until a used one surfaces is probably the only option. Otherwise....
This is simple to build without the use of special machinery.

If your system is Kf or ISO buy 2 adapters kf-tube and glass tube. If CF, look for a metal-ceramic insulator. But they are expensive.

Fabulous and idealic insulators!! While the external air insulators are a bit short, with good top field control they might go to 40kv, in air, easy!
I include an image of a couple of insulated, isolated, 2.75 CF vacuum couplings. I picked these up at HEAS flea market in my side yard two years ago. These have obvious HV insulting capabilities. I think I paid about $40.00 for everything in this image. The cross is used in the abortive fusor V of late.
