From Run 3 to the next generation: following the transformation of the LHC experiments
From dismantling detector components to installing new technologies, the transition from Run 3 to the next generation of LHC experiments is a major scientific and engineering undertaking. We follow the teams behind this transformation, exploring the challenges inside the experimental caverns and the expertise across CERN’s EP Department that helps turn ambitious upgrade plans into…

New Staff Members and Fellows – Autumn 2026
New Staff Members and Fellows – Autumn 2026 Christian Appelt Hello, I’m Christian. I’ve joined EP-ATL-SO as a Research Fellow. I completed professional training as an electronics technician, worked in industry for 5 years, and studied electrical engineering (BEng) and physics (BSc, MSc, PhD). I’ve worked at several research institutes; in ATLAS, I’ve been involved in and am leading long-lived particle searches, the production

Key4hep: A software framework for future collider studies
Key4hep brings future-collider communities together around a shared software framework for detector design and physics studies. By integrating tools for event generation, simulation, reconstruction and analysis, it reduces duplication, facilitates comparisons and allows each project to adapt the software to its own detector and scientific goals.

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

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

ROOT Users Workshop 2025
ROOT Users Workshop 2025 ROOT is a software framework at the heart of HEP’s Software Ecosystem. It is an open source project, hosted on GitHub. Laboratories such as GSI, FNAL, CERN, as well as several universities contribute to it. Moreover, many talented and motivated individuals develop ROOT: during 2025, more than 90 distinct contributors made

G4HepEm: accelerated electromagnetic shower simulation for the HL–LHC
G4HepEm: accelerated electromagnetic shower simulation for the HL–LHC When the High–Luminosity LHC (HL–LHC) starts delivering data, the volume of simulated events required to control systematic uncertainties will rise sharply. In ATLAS, detailed detector simulation already consumes a large fraction of the computing budget; in CMS, it is expected to grow substantially with the Phase-2 upgrade,

CLUE: A Scalable Clustering Algorithm for the Data Challenges of Tomorrow
CLUE: A Scalable Clustering Algorithm for the Data Challenges of Tomorrow The foreseen increase in luminosity and pileup at the High-Luminosity Large Hadron Collider (HL-LHC) [1] will challenge both the detector hardware and the reconstruction software. With higher pile-up, calorimeter energy reconstruction depends even more on pattern-recognition algorithms. These algorithms have to cluster together deposits

RNTuple: The New Columnar Storage for HEP Data
RNTuple: The New Columnar Storage for HEP Data R&D activities are vital for the ROOT project. A few years ago, we started investigating the evolution of TTree, ROOT’s columnar format with which more than two exabytes of data were written at the LHC: experiments write data, lots of it, to then store them on media

Unveiling the Power of Software in Science: Inside the EVERSE Network
Unveiling the Power of Software in Science: Inside the EVERSE Network Researchers across all sciences use different types of tools: benches, centrifuges, lasers, weather balloons, seismographs, telescopes… you name it. At CERN, such a “hardware tool” is the LHC, together with all our other accelerator facilities, which are invaluable for exploring the world of particles.
