RF Magnetron Ion Source (A Carl Willis Clone)

<r>This was my take on Carl's most recent RF Ion Source (seen here: <URL url="http://www.fusor.net/board/viewtopic.php?f=12&t=5047#p32355"><LINK_TEXT text="viewtopic.php?f=12&t=5047#p32355">http://www.fusor.net/board/viewtopic.php?f=12&t=5047#p32355</LINK_TEXT></URL> ), admittedly mine i...

Another Tubbs Special: The MOltaplier, 300kV edition.

<r>Got bored afew months back and decided I "needed" to build a 10-stage mains frequency multiplier good to about 300kV @ tens of mA. Also, I didn't want to spend more than about $50 or so, so I went and collected the carcasses of afew microwaves for their guts. Using a Pole-Piglet (potential transf...

DC-HVDC Converters for Sustaining Ion Pumps

<t>It's been awhile since I posted, and by the looks of things around here I figured you folks could use something neat.<br/> <br/> I needed to get an ion pump (some kind of ion diode pump, normal or standard I don't know which (or really care)) operating to sustain a guide while it sits around wait...

Re: Wieder Labs?

<t>Concern has already been raised about the (shoddy) quality and workmanship of Wieder products, obvious and inexcusable faults for an extraordinary price...<br/> <br/> Andrew & David's experience further my opinion that we're dealing with an unscrupulous third party seller pandering to uninfor...

Re: Archived - First neutrons from Slovakia!

<t>I would like to extend my congratulations aswell.<br/> <br/> I too am very interested in that PEM electrolysis setup, I had gone the Hoffman-apparatus route a few years ago and since then these PEMs have become widely available.

Re: DIY Viewport - Photos

<t>Most viewports use a glass to metal seal, I've never seen one with an o-ring.<br/> <br/> Regardless, I'm a big proponent of JB-Weld, I've used it on numerous occasions with zero evidence of leaks. I'd dare to call it the new and improved parchment sealing wax of vacuum assemblies. <br/> <br/> Kud...

Re: Archived - Fusor progress, info & photos

<t>Oh my, my mistake it appears you've since changed the photos you use to advertise your product to something other than Brian Mcdermott and Richard Hull's intellectual property. While I don't recognise this "batch," that doesn't mean you haven't stolen these aswell. Carry on then you vulture.<br/>...
