Problems and Solutions: The CMS ECAL lessons
Problems and Solutions: The CMS ECAL lessons The story starts in September 2022 while, during the ECAL Operations meeting our veteran electronics expert, Evgueni Vlassov reported that the voltage in one of the control cards was unstable. He prophetically proposed that the cause might be water in the circuits. A few days later, an alarm

ISOLDE lays the ground for CP violation tests with radioactive molecules
ISOLDE lays the ground for CP violation tests with radioactive molecules All atoms heavier than bismuth, which has 83 protons, are radioactive and their isotopes have short half-lives, with few exceptions. As a result, the study of heavy atoms and their molecular compounds is complicated by the radioactive decay of the nuclei, which presents a

First Physics Results from the FASER Experiment
First Physics Results from the FASER Experiment FASER is a new small LHC experiment designed to search for light, weakly interacting, long-lived beyond-standard model particles such as dark photons and to detect high energy neutrinos produced in proton-proton collisions. The FASER detector is located approximately 480m from the ATLAS interaction point along the beam collision

ANUBIS: a guide into the dark sector
ANUBIS: a guide into the dark sector The ancient Egyptians believed Anubis was a jackal-headed god who accompanied kings to the underworld. Today we know better: ANUBIS is a proposed extension to the ATLAS detector to explore the dark sector by searching for long-lived particles (LLPs). What are LLPs and why should we care? Long-lived

Lighting the dark with NA64: news from Light Dark Matter searches
Lighting the dark with NA64: news from Light Dark Matter searches The existence of Dark Matter (DM) has been inferred by Cosmology and Astrophysics through its gravitational effects. However, its microscopic nature remains one of the most pressing questions in particle physics. Scenarios in which the DM is a thermal relic from the early universe

Upgrading the CMS Electromagnetic Calorimeter Readout Electronics for Phase-2
Upgrading the CMS Electromagnetic Calorimeter Readout Electronics for Phase-2 The CMS electromagnetic calorimeter (ECAL) was designed to provide excellent energy resolution for electrons and photons in the challenging, high-radiation environment of the Large Hadron Collider [1]. In particular, the excellent design energy resolution of the CMS ECAL was aimed at the discovery of the Higgs

Radioactive ion beams at ISOLDE bring the nuclear clock a tick closer
Radioactive ion beams at ISOLDE bring the nuclear clock a tick closer The precise measurement of time and frequencies has always played an important role in the history of science. Since the adoption of the caesium-133 standard as the definition of the second within the Système International (SI) in 1967, a network of atomic clocks

ATLAS Tile Calorimeter Phase II Upgrade: entering production phase.
ATLAS Tile Calorimeter Phase II Upgrade: entering production phase. The start of the High Luminosity LHC is approaching at a fast pace. In order to be ready with its upgraded front-end electronics and data acquisition systems, ATLAS Tile Calorimeter (TileCal) community is now entering the production phase, after a long R&D period and many design

The LISA project at CERN-ISOLDE
The LISA project at CERN-ISOLDE The LISA (Laser Ionisation and Spectroscopy of Actinides) consortium aims to train a new generation of experts in radioactive ion beam research and applications, laser spectroscopy, scientific laser technologies and atomic theorists whilst they work towards the goal of vastly improving our understanding of the atomic and nuclear properties of
