Among future collider proposals, the Muon Collider stands out for its unique potential in advancing energy frontier research. However, a major challenge arises from Beam-Induced Background (BIB), caused by muon decay along the beam pipe, which complicates detector design and event reconstruction. Despite the use of tungsten conical absorbers (nozzles) in the forward regions, an irreducible...
Relativistic particles passing through crystalline structures experience a Lorentz-boosted external electric field. For high-Z crystals, if the impinging angle relative to a lattice axis is up one degree, the strong field (SF) felt by electrons and photons at an order of few GeV or higher can overcome the Schwinger limit, where the QED effects become nonlinear, and enhance the standard...
The POKER (POsitron resonant annihilation into dark mattER) project aims to perform a missing-energy measurement employing a $\sim$100~GeV positron beam impinging on an active thick target. The beam interaction with this detector could produce feebly interacting massive particles, exiting from it undetected and carrying away a significant fraction of the primary positron energy. The crucial...
Calorimeters at future Higgs factories will require excellent energy resolutions to discriminate W and Z boson hadronic decays. The Particle Flow Algorithm (PFA), which integrates data from various subsystems, is well-suited for this task. This contribution presents the development of a hadronic calorimeter made of resistive Micro Pattern Gas Detectors (MPGD) designed for experiments at...
The IDEA apparatus, a proposed experiment for the future FCCee accelerator, recently incorporated a novel electromagnetic calorimeter into its baseline design. This calorimeter aims at improving the energy reconstruction for neutral particles to 3 % at 1 GeV, while simultaneously enabling particle-flow algorithms through fine segmentation.
Designed to fit inside the magnet coil, the crystal...
Dual-readout (DR) calorimetry is one of the technologies of interest for the next generation of leptonic colliders such as FCC-ee. This calorimeter uses both scintillation and Cherenkov signals to correct for electromagnetic fraction fluctuations in hadronic showers, significantly improving the accuracy of energy measurement. Several prototypes and beam-test campaigns were conducted to...
The Deep Underground Neutrino Experiment (DUNE) is a next-generation neutrino oscillation long-baseline experiment designed to measure the neutrino mass ordering, the CP-violating phase in the lepton sector of the Standard Model and to improve the precision on key parameters that govern neutrino oscillations. The System for on-Axis Neutrino Detection (SAND) at the DUNE Near Detector complex is...
The ROSSINI project (Remotely-operated On-board Inspections for Special Nuclear Material) is designed to revolutionize the detection of illicit Special Nuclear Material (SNM) in cargo containers by integrating advanced aerial and ground-based robotic systems.
This innovative approach leverages radiation-sensitive detectors mounted on remotely operated drones and terrestrial robots to...
The DIANA (Development of a sustaInable Amorphous Novel scintillAtor) project aims to develop a novel hybrid scintillator that combines the advantages of organic and inorganic scintillators by leveraging scintillating crystal fragments. This dense, optically continuous material will be scalable to large dimensions, easily machinable into desired shapes, and economically competitive. The...
Plastic scintillators primarily consist of a fluorophore—which absorbs and converts the kinetic energy of particles into lower-energy light—dissolved in a polymer matrix, with the frequent addition of a wavelength shifter. Despite the numerous advantages offered by plastic scintillators, including fast scintillation signal, low cost and ease of manipulation and shaping, they are characterized...
Most future projects for hadronic calorimeters involve the use of multi-channel photodetectors (SiPMs) to achieve high readout granularity, allowing for improved jet resolution and better access to the substructure of overlapping jets.
Reading out each individual channel, especially for large calorimeters, would result in an uncontrollable and prohibitive increase in the number of channels to...
The PHeSCAMI project (Pressurized Helium Scintillating Calorimeter for AntiMatter Identification) aims to identify anti-deuterium in cosmic rays by exploiting the existence of delayed annihilations (~μs) expected in a pressurized helium target. The technique relies on measuring the helium scintillation signal (80 nm), which requires a two-stage WLS (Wavelength Shifter) conversion. This...
