IIHE PhD student Stef Duponcheel received the prestigious Robert Brout prize from the Solvay Institutes award at the VUB graduation ceremony on 6 October 2025, honouring a master student in physics with an excellent academic record and an inspiring dissertation. Congratulations, Stef!

I just had a tour around the DESY labs where parts of the next trackers (ATLAS and CMS) are being constructed. Amazing setups and professionalism 🤩
Every picture has an enormous amount detail behind it. Super nice to see it in real life (thanks to Elisabetta and Doris 🙏).

Fresh doctors Dr Eduardo Ploerer and Dr Kunal Gautam with their two (of many) supervisors

Completing a PhD is always a journey with ups and downs. But I am extra proud of

Dr Eduardo Ploerer ⭐️
Dr Kunal Gautam⭐️

They started PhD during a pandemic, changed official supervisor twice, and moved country 3 times. And did excellent work on detectors, algorithms & physics of FCC-ee #PhDone

Neon lights up the LHC!
CMS scientists study the first-ever neon-neon collisions, and comparing to oxygen-oxygen, xenon-xenon, and lead-lead, find interesting insights into quark-gluon plasma – the hottest state of matter🌡️

It establishes that if they exist and decay withing the CMS tracking detector, they would be produced in less than 0.01% of all Higgs boson decays. 3/4

In a first search of its kind at the LHC, the CMS experiment
looks for light beyond-the-standard-model particles with a mass in the GeV range that decay into charged hadrons and muons. 2/4

🔬 Après dix ans de construction, JUNO, le plus grand détecteur de neutrinos, est opérationnel: Une étape historique en physique des particules! ⚛️

Bravo à l'équipe IIHE-ULB, dirigée par Barbara Clerbaux, pour ces années de travail! 👏
L’analyse des premières données est déjà en cours... 👀🌌🪐

🤩 In a first-of-its-kind search at the LHC, CMS probed Higgs boson decays to new light particles that give charged hadrons and muons. The results: such decays, if they occur at all, are limited to less than 0.01% of all Higgs boson decays. Read more: cms.cern/news/hunting...

Jiangmen Underground Neutrino Obesrvatory (JUNO) : pictures of the electronic room & the detector featuring IIHE people.

The ULB JUNO group is delighted to share an important milestone for JUNO, the world’s largest underground neutrino detector. After ten years of design and construction, the JUNO experiment started data taking on 26/08/25, with the central detector fully filled with 20K tonnes of liquid scintillator.

Gilles De Lentdecker has been elected as the project manager of the CMS muon system, which is one of the key parts of the CMS experiment. Congratulations Gilles !

Des scientifiques de l’ULB contribuent au nouveau détecteur du CERN - Actualités de l'ULB

🔬 L’ULB participe à la construction de la nouvelle version du CMS, l'un des deux grands détecteurs de particules du @cern.bsky.social: 1.600 modules de haute précision à produire en 2 ans 💥

Un défi relevé avec 40 scientifiques belges, dans le cadre d’un projet soutenu par le FNRS et le FWO.

📍Last week, the Pole was met with some bright green auroras. The winterovers have also been regularly visiting and documenting conditions at the IceCube Upgrade drill camp.
