The upgraded ALICE TPC
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. Therefore, it is a true 3-dimensional tracking device which also, by recording many

Chips on a ladder: end of production for ALICE-MFT
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 commissioning at CERN. In order to limit

LHC experiments ramp-up activities
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 continue working in the lab to ensure continuation of critical activities as well as a smooth

New physics opportunities with heavy-ion collisions at the LHC
New physics opportunities with heavy-ion collisions at the LHC The LHC is the latest scientific tool in a long line of increasingly sophisticated machines built over the last 70 years to study the inner workings of our Universe and the laws governing its microscopic structure and evolution. Decades-long experimental and theoretical efforts have given rise

Heterogeneous computing efforts for high-energy physics experiments
Heterogeneous computing efforts for high-energy physics experiments Substantial improvements to the current experiments at the LHC are underway, and new experiments are being proposed or discussed at future energy-frontier accelerators to answer fundamental questions in particle physics. At future hadron colliders, complex silicon vertex trackers (3D and 4D) and highly granular calorimeters must operate in

The ALICE ITS upgrade: Pixels for quarks
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 characteristics of the high density, high temperature phase of strongly interacting matter, the quark-gluon

ALICE trigger system: Present and Future
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 objective of the ALICE experiment

“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

Anti-nuclei in the cosmos and at the LHC
Anti-nuclei in the cosmos and at the LHC The ALICE collaboration has recently released several measurements on the production of anti-deuterons and anti-3He in proton-proton and Pb-Pb collisions at LHC energies. These results are not only interesting for the study of the hot QCD medium produced in heavy- ion collisions, but they also provide crucial

Heavy-ion collisions at Quark Matter 2018
Heavy-ion collisions at Quark Matter 2018 BROKEN IMAGE NOT MOVED (drupal url : https://ep-news.web.cern.ch//content/heavy-ion-collisions-quark-matter-2018) CERN experiments presented their latest results from the study of lead-ion collisions at the annual Quark Matter conference, that was held this year in Venice, Italy. The programme includes a plethora of presentations on a variety of topics, spanning QCD at
