Nature’s Ultra-Rare Isotopes Can’t Hide From This New Particle Accelerator

A new particle accelerator at Michigan State University is producing long-awaited results. It’s called the Facility for Rare Isotope Beams, and it was completed in January 2022. Researchers have published the first results from the linear accelerator in the journal Physics Review Letters. Physicists sometimes describe isotopes as different flavors of the same element. An … Read more

Helium’s chilling journey to cool a particle accelerator

A schematic of the LCLS-II cryoplant. Credit: Greg Stewart/SLAC National Accelerator Laboratory Today it only takes one and a half hours to make a superconducting particle accelerator at the Department of Energy’s SLAC National Accelerator Laboratory colder than outer space. “Now you click a button and the machine gets from 4.5 Kelvin down to 2 … Read more

Signs of saturation emerge from particle collisions at RHIC

Members of the STAR collaboration report new data that indicate nuclei accelerated to very high energies at the Relativistic Heavy Ion Collider (RHIC) may be reaching a state where gluons are starting to saturate.

Lab successfully demonstrates new technique to improve particle beams

The beam particles each emit ultrafast light pulses as they pass through a special magnet called a pickup undulator (bottom right). Information about each particle’s energy or trajectory error is encoded in its light pulse. The light pulses are captured, focused and tuned by various light optics. The particles then interact with their own pulses … Read more

This Australian experiment is on the hunt for an elusive particle that could help unlock the mystery of dark matter

Credit: Shutterstock Australian scientists are making strides towards solving one of the greatest mysteries of the universe: the nature of invisible “dark matter.” The ORGAN Experiment, Australia’s first major dark matter detector, recently completed a search for a hypothetical particle called an axion—a popular candidate among theories that try to explain dark matter. ORGAN has … Read more

Physicists discover never-before seen particle sitting on a tabletop

Researchers have discovered a new particle that is a magnetic relative of the Higgs boson. Whereas the discovery of the Higgs boson required the tremendous particle-accelerating power of the Large Hadron Collider (LHC), this never-before-seen particle — dubbed the axial Higgs boson — was found using an experiment that would fit on a small kitchen … Read more

The standard model of particle physics may be broken — an expert explains

This article was originally published at The Conversation. The contributed the article to Space.com’s Expert Voices: Op-Ed & Insights. As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is “when are you going to find something?” Resisting the temptation to sarcastically reply “aside … Read more
