SiPM-matrix readout of two-phase argon detectors using electroluminescence in the visible and near infrared range Open
Proportional electroluminescence (EL) in noble gases is used in two-phase detectors for dark matter searches to record (in the gas phase) the ionization signal induced by particle scattering in the liquid phase. The “standard” EL mechanism…
