1229: The Largest US Particle Collider Stops Its Collisions

The Relativistic Heavy Ion Collider (RHIC), the largest particle collider in the United States, collided its last particles in early February. RHIC is a massive accelerator ring and set of instruments based at New York’s Brookhaven National Laboratory, and was designed to accelerate gold ions to near-light speed before collision. It was the second most powerful accelerator on the planet, second only to CERN’s Large Hadron Collider. Since RHIC began running in 2000, scientists have used it to study the tiniest subatomic particles, which give insight into some of the universe’s biggest questions. Brookhaven nuclear physicist Gene Van Buren joins Host Flora Lichtman to look back on the history of RHIC, what physicists have learned from the collider, and what lies ahead for particle physics.Guest: Dr. Gene Van Buren is a nuclear physicist at Brookhaven National Laboratory in Upton, New York.Transcripts for each episode are available within 1-3 days at sciencefriday.com.Subscribe to this podcast.
