The MoEDAL Experiment at the Discovery Frontier

MoEDAL, the LHC’s newest experiment [1], that started official data taking in 2015, is different to other collider detectors. It is currently comprised of passive tracking, using plastic Nuclear Track Detectors (NTDs) and trapping sub-detectors that…

ALPHA-g sees its first antiparticles: does antimatter fall up or down?

The ALPHA collaboration working on antihydrogen at the Antiproton Decelerator (AD) in building 193 has successfully expanded their setup with new devices. The previous setup consisted of a positron accumulation device, accumulating positrons from a…

OSQAR experiment sheds light on a hidden sector of CERN’s scientific heritage

Particle physics is not only confined to the high energy frontier. There are unexplored territories at ultra-low energies, of sub-eV to eV, which are also very promising, such as for example in dark matter (DM) searches. The emblematic particle of…

Experimental searches for solar and dark matter axions

Detection of solar axions If axions exist, they would be produced in large quantities in the solar interior. Photons from the solar plasma would convert into axions in the Coulomb fields of charged particles via the Primakoff axion-photon conversion…

Cloud(y) climate studies at CERN

Continuous improvements to the CLOUD facility as well as to the instruments combined with the state of the art know-how available at CERN have enabled a steady increase in the measurement capabilities and resulted in numerous high impact…

ALPHA new results: pushing the limits in antimatter research

In a paper published this week in Nature, the ALPHA collaboration reports the most precise direct measurement of antimatter ever made, revealing the spectral structure of the antihydrogen atom in unprecedented accuracy. The result…

BabyMIND records first muon tracks

Assembled as part of project NP05 at the CERN Neutrino Platform, the Baby MIND muon spectrometer has been recording its first muon tracks from neutrino interactions at J-PARC since 10th March. Baby MIND is designed to determine the momentum and…

AMS looks at Cosmic Galactic Rays

The Alpha Magnetic Spectrometer (AMS) is a state-of-the-art particle physics experiment operating on the International Space Station (ISS) since May 2011. In the first 6 years of missions, AMS has detected over 100 billion cosmic ray (CR) particles…

First positrons for GBAR

At the CERN Antimatter Factory, antihydrogen atoms are produced routinely by merging antiprotons and positrons. In order to control this process, it is necessary to reduce the energy of those particles, i.e. decelerate them to the lowest possible…

A special Xenon run for NA61/SHINE

Earlier in October, the Large Hadron Collider had a special test run of colliding xenon nuclei; a new flavour compared to the standard proton and lead collisions foreseen in the LHC experimental programme. Xenon collisions were requested by NA61, a…
