/ Broggi, G (Rome U. ; CERN ; Frascati) ; Abramov, A (CERN) ; Boscolo, M (Frascati) ; Bruce, R (CERN) ; Mirarchi, D (CERN) ; Redaelli, S (CERN)
The Future Circular electron–positron Collider (FCC-ee) is being designed to push the energy and luminosity frontiers for lepton colliders. This requires managing unprecedented intensities of lepton beams, with stored beam energies up to 17.5 MJ. [...]

This work deals with the optimization of bismuth silicate, Bi4Si3O12 (BSO) scintillation crystals as candidates for future high energy physics experiments at colliders involving the registration of both scintillation and Cherenkov light. Crystals with a high transparency in UV-band and a high timing resolution are required for this application. [...]

We demonstrate strongly collimated beam formation, at audible frequencies, in a three-dimensional acoustic phononic crystal where the wavelength is commensurate with the crystal elements; the crystal is a seemingly simple rectangular cuboid constructed from closely-spaced spheres, and yet demonstrates rich wave phenomena acting as a canonical three-dimensional metamaterial. We employ theory, numerical simulation and experiments to design and interpret this collimated beam phenomenon and use a crystal consisting of a finite rectangular cuboid array of polymer spheres 1.38 cm in diameter in air, arranged in a primitive cubic cell with the centre-to-centre spacing of the spheres, i.e. [...]

Research and Development Status for an Innovative Crystal Calorimeter for the Future Muon Collider

Accurate measurements of physical processes in high energy frontier experiments demand exceptional spatial, temporal, and energy precision to discern the physics behind high-energy particle jets. Calorimeters, like other detection systems, must be able to meet these increasingly challenging performance requirements. [...]

Advancements in TOF-PET using DOI Capable Modules and Low-Noise High-Frequency Readout
/ Terragni, G (CERN ; Vienna U.) ; Kratochwil, N (CERN) ; Lowis, C (CERN ; RWTH Aachen U.) ; Pagano, F (CERN ; INFN, Milan Bicocca) ; Cates, J W (LBNL, Berkeley) ; Pizzichemi, M (CERN ; INFN, Milan Bicocca) ; Marton, J (Vienna U.) ; Auffray Hillemanns, E (CERN)
Achieving good time resolution has become a prerequisite in positron emission tomography (PET) to improve the signal-to-noise ratio and thus the quality of the reconstructed image. A particularly attractive solution for the electronic readout is using low-noise high-frequency circuits (HF), which have demonstrated excellent timing performance in time-of-flight (TOF)-PET applications.
