Rucio crosses the exabyte horizon
Rucio crosses the exabyte horizon When we last wrote in these pages about Rucio, ATLAS had just passed the half-exabyte mark and the community counted around thirty organisations. Six years on, a threshold that was then a distant projection has been crossed: both ATLAS and CMS, the two largest LHC experiments, now each manage more

MOSAIX: Designing bent wafer-scale monolithic pixel sensors for the ALICE ITS3 upgrade
MOSAIX: Designing bent wafer-scale monolithic pixel sensors for the ALICE ITS3 upgrade The ALICE detector is preparing a major upgrade to its Inner Tracking System (ITS) during LHC long shutdown 3 (2026-2030). This upgrade, called ITS3, will replace the three innermost tracking layers with three layers of cylindrical, 50 µm thick, 27 cm long, silicon

Towards monitoring in Run 4 and beyond: LHC experiments exchange perspectives on data quality at the HL-LHC
Towards monitoring in Run 4 and beyond: LHC experiments exchange perspectives on data quality at the HL-LHC In March of 2026, experts from ALICE, ATLAS, CMS and LHCb gathered at CERN for a dedicated workshop on Data Quality Monitoring (DQM), bringing together developers, coordinators and detector specialists to discuss how the LHC experiments monitor the

Online use of AI within ALICE
Online use of AI within ALICE A reconstructed event of particles in the ALICE TPC, with data taken with the neural network cluster finding algorithm. Pink dots are reconstructed clusters. AI applications have rapidly expanded in everyday life, and ALICE, among other high-energy physics experiments at CERN, is increasingly exploring their use in fundamental physics

PUMA – Antiprotons as a precision probe for the tail of nuclear density
PUMA – Antiprotons as a precision probe for the tail of nuclear density Understanding the nuclear structure of atomic nuclei away from the valley of stability remains one of the central challenges of nuclear physics and astrophysics. In particular, the dilute outer regions of neutron-rich nuclei can exhibit phenomena such as neutron halos and neutron

New Staff Members and Fellows
New Staff Members and Fellows Maximilian Babeluk Hi, I’m Max. I recently joined the ALICE ITS3 team, where I work on sensor testing, functional verification, and in the future also chip design – particularly on MOSAIX. My main activities include testing and yield assessment across multiple integration levels (wafer probing to system tests), including data

Moving antimatter beyond the lab
Moving antimatter beyond the lab For decades, antimatter experiments have been bound to a single place: the laboratory in which the particles are produced and trapped. At CERN’s Antimatter Factory, antiprotons are routinely produced, decelerated and confined in Penning traps, where electric and magnetic fields are used to store charged particles for high-precision studies.
