4,850 feet beneath the Black Hills of South Dakota, there’s an underground particle accelerator in a former gold mine. Here, a motorcycle-riding nuclear astrophysicist named Mark Hanhardt thinks about ...

Keeping high-power particle accelerators at peak performance requires advanced and precise control systems. For example, the primary research machine at the U.S. Department of Energy's Thomas ...

From the early scattering experiments of Rutherford to the colliding beam experiments that produced the top quark with a mass almost as large as Rutherford's gold nucleus, particle beams have been the ...
