Several years back when the government was yanking the funding from the Superconducting Super Collider (A mistake in my opinion, the teeming millions could have learned a lot), I heard a story about a physicist who had built a particle accelerator in his basement (or somewhere similar) that could impart roughly the same energy (20 TeV). I remember the price tag being on the order of ten million dollars (compared to 8 billion for the SSC).
As I remember, the technology he use involved pushing the particles using the wavefronts of a laser, and not magnets like most particle accelerators. The technology wasn’t perfect in the sense that he wasn’t able to steer or control the particles well enough to collide them with each other.
Anybody know the straight dope on this? Is it possible to build a working particle collider in a basement?
