The Extreme Energy Events (EEE) experiment, a joint project of the Centro Fermi and INFN Italian national research institutes, has a dual purpose: a scientific research program for measurements of the cosmic rays flux at ground level and an intense outreach and educational program with an active contribution of students and teachers in the construction and operation of the detectors in High Schools. The network counts 60 tracking detectors, each made by three Multigap Resistive Plate Chambers (MRPC), operated so far with a gas mixture composed by 98% C$_2$H$_2$F$_4$ and 2% SF$_6$. [...]

An Inertial Uni-Axial Interferometer-Based Accelerometer for Harsh Environments / Aliana Cervera, Gerard (CERN ; Ecole Polytechnique, Lausanne) ; Solis Paiva, Santiago Andres (CERN) ; Serrano Galvez, Pablo (CERN) ; Sola Merino, Jorge (CERN) ; Butcher, Mark (CERN) ; Matheson, Eloise (CERN) ; di Castro, Mario (CERN)
For high-impact devices, subsequent vibrations have as much influence on the deterioration of the mechanical structure as the impact itself. To mitigate the consequences of both impacts and resulting vibrations, it is crucial to accurately understand the peak acceleration and vibration frequencies that originate in the structure. [...]

Students’ interest in particle physics: conceptualisation, instrument development, and evaluation using Rasch theory and analysis / Zoechling, Sarah (Vienna U. ; CERN) ; Hopf, Martin (Vienna U.) ; Woithe, Julia (CERN) ; Schmeling, Sascha (CERN)
Given the importance of fostering students’ interest as a goal of physics education in meeting international science standards, empirical support for the theoretical description of the interest construct is essential. Empirical studies require the use of psychometrically sound measurement instruments. [...]

Influence of alkali metals on water dynamics inside imidazolium-based ionic liquid nano-domains / Dziubinska-Kühn, Katarzyna (CERN ; Leipzig U.) ; Maddah, Mina (Azzahra U.) ; Pupier, Marion (Geneva U.) ; Matysik, Jörg (Leipzig U.) ; Viger-Gravel, Jasmine (Geneva U.) ; Kowalska, Magdalena (CERN) ; Karg, Beatrice (CERN ; Geneva U.)
The global need to expand the design of energy-storage devices led to the investigation of alkali metal - Ionic Liquid (IL) mixtures as a possible class of electrolytes. In this study, 1D and 2D Nuclear Magnetic Resonance (NMR) and Electrochemical Impedance Spectroscopy (EIS) as well as Molecular Dynamics (MD) simulations were used to study the intermolecular interactions in imidazolium-based IL - water - alkali halide ternary mixtures.

The PICOSEC Micromegas detector is a precise timing gaseous detector based on a Cherenkov radiator coupled to a semi-transparent photocathode and a Micromegas amplifying structure. First single-pad prototypes demonstrated a time resolution below 𝜎 = 25 ps, however, to make the concept appropriate to physics applications, several developments are required. [...]
