A European high-energy heavy-ion facility for electronics irradiation based at CERN: Concept Design Report

This proposal presents a concept design for a European high-energy heavy-ion facility dedicated to electronics radiation-effects testing, directly addressing the critical challenges of global beam time shortages and energy limitations in existing facilities. Aligned with the HORIZON-CL4-2026-SPACE-03-85 call under Horizon Europe's Cluster 4 (Digital, Industry, and Space), the facility will enhance European sovereignty in space technology by providing approximately 1,900 additional hours of heavy-ion beam time annually--a 50% increase in European capacity--and extending the accessible ion energy range up to 100 MeV/nucleon, significantly improving penetration capabilities for state-of-the-art electronics testing. The facility will leverage CERN's Low Energy Ion Ring (LEIR) synchrotron, integrating a dedicated extraction system, transfer line, and user experimental area. The project timeline includes a technical design study, followed by infrastructure and hardware production, installation, commissioning, and user operations. Funding will be secured through a collaborative framework involving CERN and the European Union, ensuring sustainable deployment and long-term operational success.

Potential for a precision measurement of solar $pp$ neutrinos in the Serappis Experiment

The Serappis (SEarch for RAre PP-neutrinos In Scintillator) project aims at a precision measurement of the flux of solar $pp$ neutrinos on the few-percent level. Such a measurement will be a relevant contribution to the study of solar neutrino oscillation parameters and a sensitive test of the solar luminosity constraint. The concept of Serappis relies on a small organic liquid scintillator detector ($\sim$20 m$^3$) with excellent energy resolution ($\sim$2.5 % at 1 MeV), low internal background and sufficient shielding from surrounding radioactivity. This can be achieved by a minor upgrade of the OSIRIS facility at the site of the JUNO neutrino experiment in southern China. To go substantially beyond current accuracy levels for the $pp$ flux, an organic scintillator with ultra-low $^{14}$C levels (below $10^{-18}$) is required. The existing OSIRIS detector and JUNO infrastructure will be instrumental in identifying suitable scintillator materials, offering a unique chance for a low-budget high-precision measurement of a fundamental property of our Sun that will be otherwise hard to access.

Acoustic detection of neutrinos in bedrock

We propose to utilize bedrock as a medium for acoustic detection of particle showers following interactions of ultra-high energy neutrinos. With the density of rock three-times larger and the speed of sound four-times larger compared to water, the amplitude of the generated bipolar pressure pulse in rock should be larger by an order of magnitude. Our preliminary simulations confirm that prediction. Higher density of rock also guarantees higher interaction rate for neutrinos. A noticeably longer attenuation length in rock reduces signal dissipation. The Pyhäsalmi mine has a unique infrastructure and rock conditions to test this idea and, if successful, extend it to a full-size experiment.

Cosmic-ray muon flux at Canfranc Underground Laboratory

Residual flux and angular distribution of high-energy cosmic muons have been measured in two underground locations at the Canfranc Underground Laboratory (LSC) using a dedicated Muon Monitor. The instrument consists of three layers of fast scintillation detector modules operating as 352 independent pixels. The monitor has flux-defining area of 1 m${}^{2}$, covers all azimuth angles, and zenith angles up to $80^\circ$. The measured integrated muon flux is $(5.26 \pm 0.21) \times 10^{-3}$ m${}^{-2}$s${}^{-1}$ in the Hall A of the LAB2400 and $(4.29 \pm 0.17) \times 10^{-3}$ m${}^{-2}$s${}^{-1}$ in LAB2500. The angular dependence is consistent with the known profile and rock density of the surrounding mountains. In particular, there is a clear maximum in the flux coming from the direction of the Rioseta valley.
