They developed this machine which was only about this big [~1 meter] and they used ultra-lightweight materials, and it only weighed about 50 kg. So c… - Suzie Sheehy

Nowadays you wouldn't want to do that voluntarily, and you wouldn't want to do it without understanding the consequences, but there are some situations that you might want to do it in... [T]here's a very good reason for that, because if you take a much lower energy beam that the Large Hadron Collider beam, and you put it into water, or into the human body, or into tissue and you start it with the correct amount of energy, it will actually slow down and stop, and deposit almost all of its dose (or its energy) in one spot... [W]e call this the .

[S]ometimes some of our craziest ideas, and I've been through some pretty crazy ideas of things that you could do with a particle accelerator here... [S]ometimes they turn out to be surprisingly good ones if you do them in the right way, and these machines are not just useful for particle physics. They're useful for all sorts of other things like cancer treatment, like killing bacteria in food, and other things I haven't discussed like carbon dating, and imaging down to the atomic scale, and all sorts of other things...

In physics I use this energy range of s which means the energy an electron would gain if I put it through a potential of 1 . So MeV is million electronvolts. And that's the scale of that... [cyclotron] they're standing next to...
