A working home built linac

Warning: The following post contains procedures that should not be attempted with out a thorough and COMPLETE understanding of the radiation hazard involved.
High vacuum is required to make this method work.
Remote operation procedure HAVE to be in place from the beginning.
Appropriated warning signs with a flashing warning light are necessary.
High voltage safety will be stringent due to the extra high potentials involved.
The radiation is short range but very intense close to the linac and the experintal area
Proper safety interlocks with keys are a must.
The local radiation will be on the order of 100 Rads or above.
It exceeds the lifetime permissible dose many fold.

Think a linac is so far into fantasy land it is impossible.... think again.
There must be something in the water here in Memphis Tenn.
Here is what a high school kid in my area did for science fair in HS....his recreation of the Walton Crockcroft accelerator of 1932 vintage with up to date parts...Enjoy.

Still think linacs are goofy?

It should be noted that this person used a -100kV power supply to accelerate the protons. I doubt your fusor's inner grid will have -100 kV on it, so I'm not sure if this type of accelerating arrangement could be made to work in a fusor. His setup is obviously much simpler than drift tubes, but drift tube accelerators may be the only option for a fusor.

I know but it shows what can be done.
Just think what he could have done with a real ion source.
I would not take this exact tact but it is interesting he built a 100kv
multiplier and actually used it. It is the essence of a beam collider fusor. In fact if you built two sets of them with two duoplasmatrons you end up with the collider Richard Hull is working on. I'm still doing drift tubes tho. Designing tube style oscillators of high power.

Is there a separate thread on this collider device? It sounds interesting...

Can you link me to the papers or info on the duoplasmatron?

Our idea here is to acquire ion gun skills and hone our techniques in same using pure glass structures at incredibly whimpy power levels. Only when we feel confident in our ion gun ideas will be go to metal and then hone skills anew. Finally a collider should be in the works.
