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. 

The CERN Axion Solar Telescope (CAST) aims to shed light on a 30 year old riddle of particle physics by detecting axions originating from the 15 million degree plasma in the Sun's core.

n_TOF one year after - First results

by Frank Gunsing

Since the termination of the construction of the new second experimental area EAR2 of n_TOF in July 2014, the facility has been successfully taking data both in the existing experimental area EAR1 and in the new EAR2. Frank Gunsing gives an overview of the latest physics results.

COMPASS-II: A QCD Laboratory at CERN

by Gerhard Mallot & Oleg Denisov, COMPASS Spokespersons

With COMPASS-II CERN enters in the exploration of a new territory: the structure of the proton in multiple dimensions. Following previous studies of the polarization of quarks and gluons; now the focus has shifted to a picture of the proton in terms of additional variables.

Measurements by the BASE experiment have compared the same properties of protons and antiprotons to high precision while the ALICE collaboration has measured the difference between mass-to-charge ratios for deuterons and antideuterons, as well as for helium-3  and antihelium-3 nuclei.
