CERN Accelerating science

SME

The AEgIS Experiment

If apples fall down, do anti-apples fall up? Or do ordinary particles fall with the same acceleration as antiparticles? According to Einstein's Weak Equivalence Principle (WEP), gravity is independent of mass and composition, hence the answer to the…

CAST opens a new window into dark energy and dark matter after 11 years of operation and continuous renewal.

The Cern Axion Solar Telescope (CAST) is the only astroparticle physics experiment at CERN. It is taking data for the last 11 years searching for solar axions or other similar exotica from the dark sector, that dominate the Universe and we do not…

MoEDAL - the LHC’s Magnificent 7th Experiment

MoEDAL, the 7th and newest experiment is dedicated to the detection of the highly ionizing particle avatars of new physics such as the magnetic monopole and massive stable or metastable charged particles. Such particles originate from a number of…

The CERN-MEDICIS project

Secondary radioactive ion beams have been delivered to ISOLDE at CERN for over 40 years, for fundamental studies in nuclear structure and for applications, for instance in semi-conductors. The idea of using these beams as sources for innovative…

New light from CLOUD on climate change

In a paper published in the journal Nature, the CLOUD experiment at CERN reports on a major advance towards solving a long-standing enigma in climate science: how do aerosol particles form in the atmosphere? It is known that all cloud droplets form…

Meeting the challenges of the High-Energy ISOLDE!

The On-Line Isotope Mass Separator ISOLDE is a facility dedicated to the production, study and use of exotic nuclei located far from the valley of stability i.e. far from the species found naturally on Earth. These exotic nuclei are being studied in…

ISOLTRAP’s MR-ToF mass separator to plumb a neutron star

The mass of an atomic nucleus is one of its most fundamental properties.Via the binding energy, i.e., the difference in mass between its constituents (protons and neutrons) and the entire nucleus, it reflects the sum of all interactions present.…

GBAR - Gravitational Behavior of Antimatter at Rest

The GBAR experiment, proposing a gravity measurement of antihydrogen at the planned ELENA facility, was approved by the Research Board in May 2012. The collaboration is formed of 14 laboratories and about 40 researchers at present1. The goal of GBAR…
