> And privately designed/built/owned particle accelerators? It's definitely a new era. Well, you could build a push-pull Van de Graaff generator, hook it up to a discharge tube, hook the tube to a high vacuum pump, and there ya go, linear accelerator in the 1 MeV range. Totally doable in a garage. There are people who built a cyclotron at home. You'll need to wind a huge coil, but it's doable.
