R&D on gas usage in the LHC particle detection systems.
A wide range of gas mixtures is used for the operation of different gaseous detectors for particle physics research. Among them there are greenhouse gases like C2H2F4 (R134a), CF4 (R14), C4F10 (R610) and SF6, which are needed because they allow to…

A new CEDAR for the NA62 experiment
The NA62 experiment at CERN studies kaon decays using a decay-in-flight technique, with the primary aim of the precise measurement of the K+ → π+νν branching fraction. The kaons are delivered to the experiment in a beam of 75 GeV/c positively-…

Casting light on the dark sector of the universe
On axions The cosmologically established cold dark matter (CDM) makes about 84% of the Universe's total mass. In the era of precision cosmology, the composition of the CDM remains a mystery. Among the proposed hypothetical particles which could…

Highlights of the n_TOF 2022 data taking run
The outcome of the first year of data-taking after LS2 [1] was fruitful for n_TOF. The long beam-on period, along with the establishment of a third experimental area, the NEAR Station, resulted in a wealth of new experimental data taken at the…

ASACUSA excites antimatter hybrid atoms immersed in superfluid helium
When atoms are immersed into liquids, their atomic spectral lines at visible wavelengths become greatly broadened compared to those of single, isolated atoms. A million-fold increase in the linewidth is often observed, which obscures spectroscopic…
