Primary scintillation yields induced by particles in gas mixtures of Argon/CF at 9.5 bar
P. Amedo, S. Leardini, A. Saá-Hernández +1
We report time and band-resolved scintillation from -particles in Ar/CF mixtures at a pressure of 9.5 bar. Our results show that %-level addition of CF enables strong wa…
Report from the Workshop on Xenon Detector Searches: Steps Towards the Kilotonne Scale
A. Anker, A. Avasthi, M. Brodeur +35
These proceedings summarize the program and discussions of the ``Workshop on Xenon Detector Searches: Steps Towards the Kilotonne Scale'' held on October 25-27 2023 at SLAC…
FAT-GEMs: (Field Assisted) Transparent Gaseous-Electroluminescence Multipliers
S. Leardini, A. Sáa-Hernández, M. Kuźniak +12
The idea of implementing electroluminescence-based amplification through transparent multi-hole structures (FAT-GEMs) has been entertained for some time. Arguably, for such a techn…
On the determination of the interaction time of GeV neutrinos in large argon gas TPCs
A. Saá-Hernández, D. González-Díaz, J. Martín-Albo +15
Next-generation megawatt-scale neutrino beams open the way to studying neutrino-nucleus scattering using gaseous targets for the first time. This represents an opportunity to impro…
Cryogenic RPWELL: a novel charge-readout element for dual-phase argon TPCs
A. Tesi, S. Leardini, L. Moleri +5
The first operation of a cryogenic Resistive Plate WELL (RPWELL) detector in the saturated vapor of liquid argon is reported. The RPWELL detector was composed of a Thick Gas Electr…
Scintillation of Ar/CF mixtures: glass-THGEM characterization with 1% CF at 1-1.5 bar
P. Amedo, R. Hafeji, A. Roberts +6
Argon gas doped with 1% wavelength-shifter (CF) has been employed in an optical time projection chamber (OTPC) to image cosmic radiation. We present results obtained during the…
The cryogenic RWELL: a stable charge multiplier for dual-phase liquid-argon detectors
A. Tesi, S. Leardini, L. Moleri +4
The operation of a cryogenic Resistive WELL (RWELL) in liquid argon vapor is reported for the first time. It comprises a Thick Gas Electron Multiplier (THGEM) structure coupled to…
Novel resistive charge-multipliers for dual-phase LAr-TPCs: towards stable operation at higher gains
A. Tesi, L. Moleri, S. Leardini +5
Cryogenic versions of Resistive WELL (RWELL) and Resistive Plate WELL (RPWELL) detectors have been developed, aimed at stable avalanche multiplication of ionization electrons in du…
Development of FeO/YSZ ceramic plates for cryogenic operation of resistive-protected gaseous detectors
L. Olano-Vegas, I. Pardo, S. Leardini +9
We present a ceramic material based on hematite (FeO) and zirconia stabilized with yttria at 8% molar (YSZ), that exhibits stable electrical properties with transported cha…
Diamond-like carbon coatings for cryogenic operation of particle detectors
Sara Leardini, Yi Zhou, Andrea Tesi +6
Characterization of diamond-like carbon (DLC) coatings at cryogenic temperatures (down to 77 K) is presented, covering the electrical resistivity range of practical interest to gas…
Time and band-resolved scintillation in time projection chambers based on gaseous xenon
S. Leardini, E. Sánchez García, P. Amedo +5
We present a systematic study of the time and band-resolved scintillation in xenon-based time projection chambers (TPCs), performed simultaneously for the primary (S1) and secondar…
Bubble dynamics in Liquid Hole Multipliers
A. Tesi, E. Segre, S. Leardini +5

A new concept for the simultaneous detection of primary and secondary scintillation in time projection chambers is proposed. Its core element is a type of very-thick GEM structure…
A study about the F-estimator for the neutrino mass hierarchy in the JUNO experiment
Sara Leardini
At present, it is still unknown whether the correct mass ordering of the neutrino mass eigenstates is either , , (Normal Hierarchy, NH), or , , (Inv…
