Thermal Cesium Release in PMTs Revealed by Resonant Laser Spectroscopy and Its Correlation with Quantum Efficiency
Antonio De Benedittis, Pasquale Migliozzi, Carlos Maximiliano Mollo +1
We report optical evidence of cesium (Cs) evaporation from a bialkali (SbKCs) photo-cathode during controlled heating of a photomultiplier tube (PMT). A DFB laser scanned across th…
Light exposure and temperature effects on quantum efficiency of bialkali metal photomultipier tubes
Antonio De Benedittis, Pasquale Migliozzi, Carlos Maximiliano Mollo +2
In astroparticle experiments, photomultiplier tubes are crucial for detecting Cherenkov radiation emitted by charged particles, owing to their exceptional sensitivity to low-intens…
Measurement of neutrino oscillation parameters with the first six detection units of KM3NeT/ORCA
KM3NeT Collaboration, S. Aiello, A. Albert +260
KM3NeT/ORCA is a water Cherenkov neutrino detector under construction and anchored at the bottom of the Mediterranean Sea. The detector is designed to study oscillations of atmosph…
Search for quantum decoherence in neutrino oscillations with six detection units of KM3NeT/ORCA
S. Aiello, A. Albert, A. R. Alhebsi +259
Neutrinos described as an open quantum system may interact with the environment which introduces stochastic perturbations to their quantum phase. This mechanism leads to a loss of…
