A new experiment searching for dark matter at CERN

One of the biggest puzzles in physics is that eighty-five percent of the matter in our universe is “dark”: it does not interact with the photons of the conventional electromagnetic force and is therefore invisible to our eyes and telescopes.…

HIE-ISOLDE celebrates the end of the first stage of the energy upgrade and the great physics outcome.

There was an air of celebration at CERN on Wednesday 28th September as nearly 100 invited guests gathered to mark the successful completion of phase 1 of the HIE-ISOLDE project, which aims to provide higher intensity and energy beams, up to 5.5 MeV/…

ASACUSA Collaboration at CERN AD

ASACUSA (atomic spectroscopy and collisions using slow antiprotons) now works mainly on two subjects, 1) antihydrogen ground-state hyperfine splitting measurement, and 2) antiprotonic helium laser spectroscopy. Both of these aim at CPT tests. …

The BASE Experiment

BASE is a Japanese / German collaboration at the antiproton decelerator facility which was approved in 2013. The goal of the effort is to conduct Penning trap based high-precision investigations of the fundamental properties of protons and…

HIE-ISOLDE: Stage 1 fully installed

ISOLDE is CERN’s radioactive beam facility that produces low energy and post-accelerated beams. The high energy and intensity, average intensity of 2 μA, of the proton beam from the PS booster on different thick targets produces high quality intense…

MoEDAL releases new mass limits for the production of monopoles

In April, the MoEDAL collaboration submitted its first physics-research publication on the search for magnetic monopoles utilising a 160 kg prototype MoEDAL trapping detector exposed to 0.75 fb–1 of 8 TeV pp collisions, which was subsequently…

NA62 exploits the first high intensity kaon beam of 2015

Last May, the newsletter reported about the two-month pilot run of 2014 and how NA62 was preparing for the 2015 data taking: this became reality for five months between mid-June and mid-November, an exciting but exhausting period for our operation…

First Pb beam in NA61/SHINE

December 1st ended a two-week test period with Pb beam in the NA61/SHINE fixed-target experiment [1]. Pb ions at momentum of 30A GeV/c were delivered from the CERN SPS to the experiment for the first time. The beam time was used to perform numerous…

AWAKE starts installation

On 18 September, the CERN council approved a boost in funding for a planned experiment called the Advanced Wakefield Experiment, or AWAKE. AWAKE is a proof-of-principle experiment, whose aim is to use protons to generate powerful wakefields,…

A Timelapse video of CAST

The CERN Axion Solar Telescope (CAST) is an experiment to search for hypothetical particles called axions. These have been proposed by some theoretical physicists to explain why there is a subtle difference between matter and antimatter in processes…
