A new experiment searching for dark matter at CERN

by Stefania Pandolfi

The NA64 experiment started operations at CERN’s North Area earlier this year hunting the hypothetical dark photon

On 28th September, the ISOLDE Collaboration celebrated the completion of stage 1 of the HIE-ISOLDE project, which opens up new physics opportunities for radioactive ion beam experiments at CERN.

ASACUSA Collaboration at CERN AD

by Ryugo Hayano on behalf of the ASACUSA collaboration

The ASACUSA experiment focuses on antihydrogen ground-state hyperfine splitting measurement and antiprotonic helium laser spectroscopy, both aiming at precise CPT tests.

The BASE Experiment

by Stefan Ulmer on behalf of the BASE Experiment

BASE collaboration, approved in 2013, will conduct Penning trap based high-precision investigations of the fundamental properties of protons and antiprotons providing stringent tests of the CPT symmetry.

HIE-ISOLDE: Stage 1 fully installed

by Maria Jose Garcia Borge

The High Intensity and Energy at ISOLDE, HIE-ISOLDE, project intends to improve the experimental capabilities at ISOLDE over a wide front. The impact of the increase of energy and intensity of the injectors together with a number of improvements in several aspects of the secondary beam properties are addressed in the HIE-ISOLDE Design Study.

Recent results from the CLOUD experiment

by Panos Charitos & Jasper Kirkby

CERN’s  CLOUD  experiment publish new paper that sheds new light on cloud formation. It shows that biogenic vapours emitted by trees and oxidised in the atmosphere have a significant impact on the formation of clouds, thus helping to cool the planet.

MoEDAL releases new mass limits for the production of monopoles

by B Acharya et al. MoEDAL Collaboration

In April, the MoEDAL collaboration submitted its first physics research publication on the search for magnetic monopoles

Last May, the PH 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 team!

First Pb beam in NA61/SHINE

by Antoni Aduszkiewicz

December 1st ended a two-week test period with Pb beam in the NA61/SHINE xed-target experiment. Pb ions at momentum of 30A GeV/c were delivered from the CERN SPS to the experiment for the first time. 

The AWAKE project has been proposed as an approach to accelerate an electron beam to the TeV energy regime in a single plasma section.
