Jefferson Labs also is home to the Continuous Electron Beam Accelerator Facility, or CEBAF. The CEBAF is like a racetrack for subatomic particles. Using incredibly strong electromagnetic fields, the CEBAF revs up electrons, speeding them along the track before slamming them into something—usually, atoms of an element that the lab is studying. By recording what happens after the collision, scientists gain a greater understanding of how an atom—and, by extension, the world around us—is put together.
It’s a difficult process, to be sure. For starters, components of the CEBAF have to be incredibly cold—over 452 degrees below zero—so the Jefferson Lab contains the world’s largest refrigerator of liquid helium, which scientists use to cool things off.
Another problem is what happens once the scientists smash an atom with the CEBAF: pieces of the atom go flying off in all directions. This is what scientists want to happen; it’s how they get results. However, those atomic pieces are charged with energy, and, if they hit the wrong equipment in the lab, the electronics can get damaged. Given the sensitive nature of the lab’s equipment (remember the laser?), scientists really didn’t want it getting damaged.
To solve their problem, scientists at the Jefferson Lab turned to Hylton Builders. Using a brand-new, patented mixture of concrete—using boron carbide instead of rock in the mix—developed by scientists at the lab, Hylton Builders constructed a cement “house” to hold the Super High Momentum Spectrometer, one of the delicate (and monumentally expensive) instruments used to record data. The boron in the concrete absorbs neutron radiation from the experiments, ensuring that the subatomic particles stay where they should. Hylton Builders was the first construction company in the world to build with this kind of concrete—it’s that new.
