Hello, all. I've heard of a few renowned scientists having build small particle accelerators in their garages as teenagers, and I've wondered how I could do the same. Obviously, I'm not looking for anything LHC-scale, but rather a few feet in circumference. I've seen similar projects on the internet, but never stating how to build it, or where to start. So how would I go about creating a small, low voltage particle accelerator? How would I create the vacuum? How would I capture the starting hadrons? How would I accelerate them? How would I observe them? How would I collide them with something else? I realize that this is a very complicated topic, but I am very interesting in pursuing it. Thank you very much in advance.
