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…

MEDICIS: a new CERN facility can help medical research into cancer

Last week, the new CERN-MEDICIS facility has produced radioisotopes for medical research for the first time. MEDICIS (Medical Isotopes Collected from ISOLDE) aims to provide a wide range of radioisotopes, some of which can be produced only at CERN…

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…

How heavy is the proton?

To determine the mass of a single proton more accurately, the group of physicists from the Max Planck Institute for Nuclear Physics in Heidelberg and RIKEN in Japan performed an important high-precision measurement in a greatly advanced Penning…

Exploring the dark sector with NA64

The field of dark matter (DM) particle physics is at an interesting stage, as key discoveries are anticipated. However, despite the intensive direct, indirect and LHC searches, the experiments have not yet yielded unambiguous Dark Matter (DM)…

HIE-ISOLDE is tuning up for the new physics season

This year has been a busy one for HIE-ISOLDE, the high energy and intensity upgrade project at ISOLDE. In January 2017, another milestone was reached with the addition of the third cryomodule to the HIE-ISOLDE linear post-accelerator, increasing the…

Search for axions in streaming dark matter

Streaming dark matter (DM) axions may be the better source for their discovery than the widely assumed isotropic DM. Because, a large axion flux enhancement can take place, temporally, due to gravitational lensing when the Sun and/or a planet…

Exotic searches with NA62 experiment

The NA62 experiment at CERN focuses in the study of kaon physics; a branch of physics that has been one of the major protagonists of the field in the second half of the twentieth century, as it played a key role in the development of the Standard…

MOEDAL first results at the LHC’s discovery frontier

In 2010 the MoEDAL experiment at the Large Hadron Collider (LHC) was approved, as the LHC’s newest experiment, to start data taking in 2015. MoEDAL is a pioneering experiment designed to search for highly ionizing avatars of new physics such as…

First measurements of the antihydrogen spectrum

For many years, atomic spectroscopy allowed the determination of the composition of an element by its electromagnetic spectrum. Every chemical element has a unique `signature' which can be revealed by analyzing the light it gives off. Measuring how…
