The Physical Sciences Area seeks to understand the fundamental physics of the universe at scales ranging from the infinitely small, inside the world of subatomic particles and nuclei, to the infinitely large, in the structure and evolution of the universe. To tackle these two infinities, we develop cutting-edge tools and technologies, coupled with creative scientific insights, that advance scientific knowledge and ultimately benefit society.

Accelerator Technology & Applied Physics

Compact S-filter at Bldg. 53

The Accelerator Technology & Applied Physics (ATAP) Division invents, develops, and deploys particle accelerators and accelerator-based photon sources to explore and control matter and energy.

Engineering

The Engineering Division builds advanced scientific instrumentation that enables many of the research breakthroughs achieved by Berkeley Lab. These discoveries are the direct result of the integrated coordination and deployment of professional engineering and specialized technical resources.

Nuclear Science

Solenoidal Tracker at Relativistic Heavy Ion Collider and the Time Projection Chamber, project field cage

The Nuclear Science Division conducts basic research aimed at understanding the structure and interactions of nuclei and the forces of nature as manifested in nuclear matter.

Physics

ATLAS pixel detectors in clean room

Interactions between matter and energy shape our world and the universe around us. Physics Division researchers are studying these interactions from the innermost confines of subatomic particles to the outermost reaches of the cosmos.

In Episode 3 of the Let’s Get Nuclear podcast, NSD researchers explore the shift from traditional beta-emitting isotopes – which act like tiny BB pellets – to the high-energy power of alpha emitters, which hit cancer cells like cannonballs. But there is a catch: these potent treatments are used in such small doses that they are nearly invisible to current imaging technology.

Behind the Science: FIONA

Does the periodic table break down? To find out, Berkeley Lab researchers are using FIONA, a state-of-the-art spectrometer at the Lab’s 88-Inch Cyclotron, to study the chemistry of the heaviest elements.
