# Amateur Linac Experiment

Hello everyone,

I'd like to say hello to all the fellows here at PF, I've been reading threads in the forum for the longest time, and have joined up today.

My inquiry is of the viability of constructing a sort of linac that accelerates ionized[gas], or electrons from an electron gun and ends up hitting (possibly a phosphor coated screen) a block, or though expensive, a Faraday cup. I understand the issues of less-than-ideal vacuum conditions, and especially in the case of the Beta particle, it is a requirement for anything in particular to happen. Getting magnets to work in unison to do any type of accelerating also has it's complexities to work out.

I've read for about a week now on the matters in accelerator physics than hanging around HEP Experiment section of arXiv.org for hours, so my intuition is extremely limited, but I'm eager to overcome this temporal roadblock.

I've seen some posts on here, and I sincerely apologize for any hint of overambitious perspectives or of the sort; I just want others input.

Thanks.

-Nikos

My second post must have thrown you off:
I have experience with electronics, and playing with NST's, MIG welders, and AC sockets. I work at an airport shop, and use nitrogen bottles regularly, so anything to do with the vacuum is only under 14.7 PSI(compared to 3000 PSI). A polycarbonate tube would suffice for the vacuum cavity and would set any safety concerns-essentially-aside.

The incompetence I hold is the viability of building a small-scale linac under a $2000-$3000 budget.

What are some implications with the idea? How about it as a hypothetical question?
