Advances in subatomic physics heavily depend on ingenuity and technology. And when it comes to discovering the nature of some of the most elusive particles in the universe, neutrinos, scientists need the best and most sensitive detector technology possible. Scientists working at CERN have started tests of a new neutrino detector prototype, using a very promising technology called “dual phase.”

Scientists working at CERN have started tests of a new neutrino detector prototype using a promising technology called “dual phase.” If successful, this new technology will be used at a much larger scale for the international Deep Underground Neutrino Experiment, hosted by Fermilab. Scientists began operating the dual-phase prototype detector at CERN at the end of August and have observed first tracks. The new technology may be game-changing, as it would significantly amplify the faint signals that particles create when moving through the detector.

The Johannes Gutenberg University Mainz, Germany, has taken a significant step to participate in the international Deep Underground Neutrino Experiment, hosted by Fermilab. Fermilab and the university have signed an agreement to jointly appoint an internationally renowned researcher who will strengthen the experimental particle physics research program at JGU Mainz and advance a German contribution to DUNE. This is the first Fermilab joint agreement with a university in Germany.

Agencies in the United States and France have signed statements expressing interest to work together on the development and production of technical components for PIP-II, a major particle accelerator project with substantial international contributions. In addition, the French agencies also plan to collaborate on DUNE, an international flagship science project that will unlock the mysteries of neutrinos.

The agreement launches a multinational collaboration to build a powerful new accelerator at DOE’s Fermilab complex. Italy and its National Institute of Nuclear Physics will provide major contributions to the construction of the 176-meter-long superconducting particle accelerator that is the centerpiece of the PIP-II project.
