How will Fermilab’s new accelerator propel particles close to the speed of light?

The PIP-II project at Fermilab includes the construction of a 215-meter-long particle accelerator that will accelerate particles to 84% of the speed of light. It is the first U.S. particle accelerator project with significant contributions from international partners. Research institutions in France, India, Italy, Poland, the UK and the United States are building major components of the new machine. Superconducting radio-frequency cavities will provide the electromagnetic waves that propel particles to 800 million electronvolts. The new particle accelerator will enable Fermilab to generate an unprecedented stream of neutrinos—subtle, subatomic particles that could hold the key to understanding the universe’s evolution. It will power the scientific program for the international, Fermilab-hosted Deep Underground Neutrino Experiment (DUNE) and Long-Baseline Neutrino Facility (LBNF).
