The commissioning and installation of the new ALICE ITS

The Inner Tracking System (ITS) is the innermost detector of the ALICE central barrel. It consists of seven cylindrical layers all equipped with Monolithic Active Pixel Sensors (MAPS) named ALPIDE (ALice PIxel DEtector). The ITS allows track ing…

LHC takes on the SMEFT challenge

The quest for new physics at the LHC is entering a new phase: the experiments are designing new strategies to target potential deviations from the Standard Model (SM) predictions in a systematic way, to complement the traditional “bump hunts” and,…

ALICE gears up towards a rich Run 3 QCD programme

Quantum Chromodynamics (QCD), the theory of strong interactions, is characterised by a rich phase diagram. The elementary coloured degrees of freedom of the theory, quarks and gluons, under ordinary conditions are confined in colour-neutral hadrons…

CERN's new open data policy supports open science

The four main LHC collaborations (ALICE, ATLAS, CMS and LHCb) have unanimously endorsed a new open data policy for scientific experiments at the Large Hadron Collider (LHC), which was presented to the CERN Council today. The policy commits to…

The upgraded ALICE TPC

The ALICE time projection chamber (TPC) is a big, gas-filled cylinder (with a hole in the centre to accommodate the silicon tracker), where the charge produced by ionising radiation is projected onto detectors arranged in the two endplates.…

Chips on a ladder: end of production for ALICE-MFT

After more than four years of research and development, design and manufacturing work, the MFT (Muon Forward Tracker), a new detector that will equip the ALICE experiment at the LHC, has seen its construction finalized and is currently under…

LHC experiments ramp-up activities

Around the world,research centres, laboratories and universities have closed as a response to the COVID-19 pandemic — forcing an increasing number of researchers to work from home. Researchers teleworking coordinated with colleagues who had to…

The ALICE ITS upgrade: Pixels for quarks

Introduction ALICE, the heavy-ion dedicated experiment at the LHC, will soon have enhanced physics capabilities with a major upgrade of the detectors, data-taking and data-processing systems which will improve the precision of the extracted…

ALICE trigger system: Present and Future

The purpose of any trigger system is to select an event sample strongly enriched in physics processes of interest, while rejecting those not of interest, and to do so in such a way as to make efficient use of the available detectors. The prime…

"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…
