Investigation of the FastIC+ ASIC for timing characterisation of heterostructured scintillators and BGO / Lowis, C (CERN ; RWTH Aachen U.) ; Cardona, C (Boston U. (main)) ; Terragni, G (CERN) ; Mazzanti, D (U. Barcelona (main)) ; Ballabriga Sune, R (CERN) ; Alozy, J (CERN) ; Gómez, S (Barcelona, Polytechnic U.) ; Gascón, D (U. Barcelona (main)) ; Langen, K J (RWTH Aachen U.) ; Ziemons, K (Aachen U. of Appl. Sci., Julich) et al.
BGO and EJ-232-based heterostructured scintillators offer acombination of high detection efficiency and good timing performanceby combining the two materials in a stack of alternating micro-meterthick layers. This makes them interesting for Time Of FlightPositron Emission Tomography (TOF-PET) where γ-detectionefficiency and the Coincidence Time Resolution (CTR) are keyparameters. [...]

Enhancement of the DUNE FD1 X-ARAPUCA Photon Detection Efficiency and upgrade of the FD2 Photon Collector / Cattadori, C M (INFN, Milan Bicocca ; Milan Bicocca U.) /DUNE Collaboration
The Photon Detection System (PDS) of the first two DUNE far detectors (FD1 and FD2) is composed of 6000 and 672 photon detection units respectively, named X-Arapuca, of different size and geometry. The PDS will complement and boost the DUNE LArTPC for the detection of non beam events: the prompt light detection will improve their tagging, and at low energies it will enable the trigger and the calorimetry of the supernova neutrinos.

Scintillating sampling ECAL technology for the LHCb ECAL Upgrade II / Picatoste, E (Barcelona U.) /LHCb ECAL Upgrade II R&D; Group Collaboration
The aim of the LHCb Upgrade II is to be able to operate at a luminosity of 1.5×10$^{34}$ cm$^{-2}$ s$^{-1}$ to collect a data set of 300 fb$^{-1}$. The required substantial modifications of the current LHCb electromagnetic calorimeter due to high radiation doses in the central region and increased particle densities are referred to as LHCb ECAL Upgrade II.

Characterization of glass multigap RPC detector with alternative gas to SF6 / Verzeroli, Mattia (IP2I, Lyon) ; Guida, Roberto (CERN) ; Laktineh, Imad (IP2I, Lyon) ; Mandelli, Beatrice (CERN) ; Rigoletti, Gianluca (CERN)
Glass Multi-gap Resistive Plate Chamber detectors are primarily valued for their exceptional time resolution and are widely used in fields such as high-energy physics and tomography applications. Traditionally, these detectors are operated using Freon-based gas mixtures, primarily composed of C2H2F4 (R134a) and SF6, both classified as greenhouse gases. [...]

Evaluating the performance and long-term stability with LHC-like background irradiation of RPC detectors with CO2-based gas mixtures / Juks, Stefania A (U. Paris-Saclay) ; Guida, Roberto (CERN) ; Mandelli, Beatrice (CERN) ; Rigoletti, Gianluca (CERN) ; Verzeroli, Mattia (Lyon U.)
Resistive Plate Chamber (RPC) detectors at CERN’s LHC experiments traditionally use a Freon-based gas mixture containing C2H2F4 (R-134a) and SF6, both of which are high global warming potential (GWP) gases. To reduce greenhouse gas (GHG) emissions, operational costs, and optimise RPC performance, one possible mid-term solution is the gas mixture with a substitution of 30% of R-134a with CO2 in the standard RPC gas mixture. [...]
