Nice PIG Ion Source Example, for "Homebrew"

Post by lutzhoffman » Wed Mar 16, 2011 1:40 am


Yes I know that there are so many PIG ion source designs out there, but this one caught my eye so to say, since it looks to be rather easy to build, and it uses common available materials with no "exotic" machining requird. Personally I prefer RF / microwave excited sources, like the prior designs posted by Carl, and Doug, but for fusor, or simple accelerator use, (where a spread in ion energy can be tollerated), then this one should work fine. It could be built with a very small investment in capital and equipment, plus it delivers a full ma, if the paper is to accurate . It looks very similar to one that I saw a while back, which was used in a sealed neutron tube for well logging via the DD, and DT fusion reaction. Enjoy : )

Thanks for posting this! It looks like it would be simple to build and useful for a number of different projects here.

They didn't use a faraday cup with electron suppression so the reported beam current is more likely to be a third of what they claim due to secondary electron emission off their collector plate
