The LS2 period for the ATLAS detector
The LS2 period for the ATLAS detector The main upgrade activities are all aimed at enhancing the capability of the detector to trigger more efficiently on leptonic and hadronic signatures. In particular it is essential to preserve the ability to trigger efficiently on electron and muons with transverse momentum of ~20 GeV. With the instantaneous

LHCb plans for major upgrade during LS2
LHCb plans for major upgrade during LS2 During the previous LHC runs, the LHCb experiment collected 10 fb-1 and performed many important measurement in the heavy flavour sector. However, many crucial measurements are statistically limited, with experimental precision not directly comparable to the uncertainty of the theoretical predictions. In order to significantly increase the statistical

“New” ALICE coming to life during LS2
"New" ALICE coming to life during LS2 The ALICE solenoid re-opens its door as the collaboration prepares for the detector upgrade planned for LS2. At 6 a.m. on December 3, 2018, the LHC expert team switched off the engine of the biggest particle accelerator in the world, which will rest for the next two years

ALPHA-g sees its first antiparticles: does antimatter fall up or down?
ALPHA-g sees its first antiparticles: does antimatter fall up or down? The ALPHA collaboration working on antihydrogen at the Antiproton Decelerator (AD) in building 193 has successfully expanded their setup with new devices. The previous setup consisted of a positron accumulation device, accumulating positrons from a sodium radiative source, a dedicated catching trap to receive

HL-LHC computational challenge for ATLAS and CMS experiments
HL-LHC computational challenge for ATLAS and CMS experiments The two general purpose LHC Experiments, ATLAS [1] and CMS [2], are going to be confronted with challenging experimental conditions at the High Luminosity LHC Run (HL-LHC), starting in 2026. In particular, computing systems will have to cope with greatly increased data samples and data acquisition and

Meeting the challenges of tracking detector mechanics
Meeting the challenges of tracking detector mechanics Designing detectors to meet the physics requirements of future high-energy experiments calls for a strong R&D program on new detector-systems. This includes sensors technologies, fast and efficient electronics, mechanics and cooling techniques that could cope with the environment offered in high-energy and high-intensity colliders planned for the post-LHC

ProtoDUNE sees first particle tracks
ProtoDUNE sees first particle tracks Introduction The CERN Neutrino Platform was installed in 2014 following the recommendation of the European Strategy Group for CERN to engage in the worldwide experimental neutrino program. The platform engaged from the start in the future Deep Underground Neutrino Experiment (DUNE) in the US, which plans for its far detector

Interview with Claudia de Rham
Interview with Claudia de Rham For one week in November, Geneva hosted the 18th edition of the annual Wright Colloquium. This year’s theme was “Gravity” The Universal Attraction” and gathered researchers and thinkers to present their research and share some of the questions that intrigue them while showing off the most fascinating data that could

Particle colliders join the quest for dark energy.
Particle colliders join the quest for dark energy. The birth of a new science The beginning of the twentieth century was marked by two of the greatest scientific discoveries: quantum mechanics and the theory of relativity, which became the driving forces behind an array of new scientific breakthroughs and technological leaps. Quantum mechanics led to

First particle tracks seen in prototype for international neutrino experiment
First particle tracks seen in prototype for international neutrino experiment The largest liquid-argon neutrino detector in the world has just recorded its first particle tracks, signaling the start of a new chapter in the story of the international Deep Underground Neutrino Experiment (DUNE). DUNE’s scientific mission is dedicated to unlocking the mysteries of neutrinos, the
