VANCOUVER, B.C. – Dr. Nigel Smith, Executive Director of SNOLAB, has been selected to serve as the next Director of TRIUMF. Succeeding Dr. Jonathan Bagger, who departed TRIUMF in January 2021 to become CEO of the American Physical Society, Dr. Smith's appointment comes as the result of a highly competitive, six-month international search. Dr. Smith will begin his 5-year term as TRIUMF Director on May 17, 2021.

The COHERENT particle physics experiment at the Department of Energy’s Oak Ridge National Laboratory has firmly established the existence of a new kind of neutrino interaction. Because neutrinos are electrically neutral and interact only weakly with matter, the quest to observe this interaction drove advances in detector technology and has added new information to theories aiming to explain mysteries of the cosmos.

Accelerator physicist Chuyu Liu, the run coordinator for this year's experiments at the Relativistic Heavy Ion Collider (RHIC), in the Main Control Room of the collider-accelerator complex at Brookhaven National Laboratory.
UPTON, NY—Accelerator physicists are preparing the Relativistic Heavy Ion Collider (RHIC), a DOE Office of Science user facility for nuclear physics research at DOE’s Brookhaven National Laboratory, for its 21st year of experiments, set to begin on or about February 3, 2021. Instead of producing high-energy particle smashups, the goal for this run is to maximize collision rates at the lowest energy ever achieved at RHIC.

The Dark Energy Survey, a global collaboration including the Department of Energy’s Fermi National Accelerator Laboratory, the National Center for Supercomputing Applications, and the National Science Foundation’s NOIRLab, has released DR2, the second data release in the survey’s seven-year history. DR2 is the topic of sessions today and tomorrow at the 237th Meeting of the American Astronomical Society, which is being held virtually.

Before DESI, the Dark Energy Spectroscopic Instrument, can begin its 5-year mission from an Arizona mountaintop to produce the largest 3D sky map yet, researchers first needed an even bigger 2D map of the universe.

TRIUMF’s Advanced Rare Isotope Laboratory (ARIEL)
Vancouver — Scientists and engineers at TRIUMF, Canada's particle accelerator centre, announced a major milestone for TRIUMF's Advanced Rare Isotope Laboratory (ARIEL), maneuvering for the first time an isotope beam through the ARIEL-based CANREB facility and on to an experiment.
The achievement marks a watershed moment for the laboratory's future-facing science program, which leverages TRIUMF's unique accelerator infrastructure to drive impact from research on short-lived rare isotopes.

The U.S. Department of Energy has formally approved the scope, schedule and cost of the PIP-II project at Fermilab. The PIP-II accelerator will become the heart of Fermilab’s upgraded accelerator complex, delivering more powerful proton beams to the lab’s experiments and enabling deeper probes of the fundamental constituents of the universe.

Led by the Department of Energy’s Oak Ridge National Laboratory, a new study clears up a discrepancy regarding the biggest contributor of unwanted background signals in specialized detectors of neutrinos. Better characterization of background could improve current and future experiments to detect real signals from these weakly interacting, electrically neutral subatomic particles and understand their role in the universe.

Interactions Collaboration Member laboratories are lending their knowledge, technology, and expertise to the global effort against the novel coronavirus, COVID-19. They are analyzing the virus with detectors, helping evaluate data through advanced computing, and even producing personal protective equipment for medical personnel.

This year, October 31 was more than just Halloween. It was also the first global celebration of Dark Matter Day. In 25 countries, 11 US states and online, people interacted with scientists, watched demonstrations, viewed films, took in art exhibits and toured laboratories to learn about the ongoing search for dark matter.
Symmetry has collected a series of photos from participants around the world. Check out how people celebrated Dark Matter Day and download a commemorative dark matter poster (to be printed using visible matter).
