New Staff Members and Fellows
New Staff Members and Fellows Joshua Falco Beirer Joshua is a Research Fellow working on the development of high precision fast calorimeter simulations. He received his PhD in physics within the Wolfgang-Gentner programme at CERN and has been a member of the ATLAS collaboration since his undergraduate days. He has been actively involved in various

Investigating exotic structures of exotic nuclei with Miniball
Investigating exotic structures of exotic nuclei with Miniball Atomic nuclei come in all manner of shapes and sizes, sometimes at the same time! The reason behind this diversity lies in poorly understood nuclear forces. Many features of these forces only came to light when studying very unstable nuclei, which do not occur terrestrially. At CERN,

SHADOWS of New Physics in the CERN North Area
SHADOWS of New Physics in the CERN North Area In recent years, the physics of feebly-interacting particles (FIPs) has received considerable and growing attention from the broad HEP community, motivated by both existing data, and by the appeal of simple extensions of the Standard Model to address long-standing puzzles in which FIPs play an important

CLOUD experiments show that trees can make their own clouds.
CLOUD experiments show that trees can make their own clouds. Atmospheric aerosols are tiny solid or liquid droplets suspended in the air. They are all around us, emitted from a variety of natural and anthropogenic sources. Although aerosol particles are too small to be seen with the human eye, they have a significant impact on

A word from the EP Deputy Department Head – December 2023
A word from the EP Deputy Department Head – December 2023 As we look back on 2023, we can reflect on a year with many challenges, but also many achievements, that you can read about in this December edition of the EP newsletter. The flagship CERN accelerator, the LHC, had a year of two halves,

The ATLAS New Small Wheel – Triggering on muons and rejecting fakes
The ATLAS New Small Wheel – Triggering on muons and rejecting fakes The New Small Wheel (NSW) [1] has been the largest Phase-1 upgrade project of ATLAS. The two innermost stations of the Endcap Muon spectrometer have been replaced with two newly built detector systems based on small-strip Thin Gap Chambers (sTGC) and Micromegas (MM).

Pushing the boundaries of monolithic CMOS sensor technologies
Pushing the boundaries of monolithic CMOS sensor technologies Silicon solid state detectors have been developed over a long time to address the challenges of particle tracking and vertexing. At the LHC, when the machine reaches its full design regime, it collides proton bunches at a rate of 40 million times per second. To capture these

First analysis of Run 3 data with a new slim data format
First analysis of Run 3 data with a new slim data format The ATLAS Collaboration has just released a new measurement of the production cross-section of two Z bosons. This result examines data collected during Run 3 of the LHC – with protons colliding at a record energy of 13.6 TeV – and pioneers the

Asterix in Switzerland
Asterix in Switzerland This episode of the adventures of the winged-helmed Gaul was published in 1970 and foretold what would happen 28 years later, when the CERN microelectronics group (MIC at the time, now the ME section in EP-ESE) welcomed the arrival of its first X-ray irradiation system. The need for such equipment emerged with

LHCb’s new VELO preparing to spring into action
LHCb's new VELO preparing to spring into action The replacement of the previous VErtex LOcator (VELO) detector with a new high-speed hybrid pixel detector was one of the key milestones for the LHCb collaboration in 2022 (see also previous EP newsletter article). The upgrade was part of an R&D programme that allows the LHCb detector
