Fermilab gets ready to upgrade accelerator complex for more powerful particle beams

Fermilab's accelerator complex has achieved a major milestone: The U.S. Department of Energy formally approved Fermi National Accelerator Laboratory to proceed with its design of PIP-II, an accelerator upgrade project that will provide increased beam power to generate an unprecedented stream of neutrinos--subatomic particles that could unlock our understanding of the universe--and enable a broad program of physics research for many years to come.
