What makes Jefferson Lab's electron beam go? Niobium cavities, like this one, kick the electrons in the beam as they pass through them. Every time an electron gets kicked, it gets a little more energy. Each cavity is about half a meter long and costs about $30,000. Most of the accelerator's 338 cavities can be found in the long, straight sections.
