Some novel ideas of ionization-electron and scintillation-photon sensing concepts in single-phase noble-liquid detectors are presented. They rely on immersed micro-structured electrodes, including ones undercoated with VUV photocathodes. Both, radiation-induced electrons from the liquid and primary-scintillation photoelectrons emitted by the photocathode are collected on thin anode strips or...
We describe a novel concept for dual-phase noble liquid detectors, the Floating Hole Multiplier (FHM). It consists of a perforated electrode freely floating on the surface of the liquid. The concept has been validated with a Thick Gas Electron Multiplier (THGEM) on the surface of liquid xenon. First experimental results will be reported showing that the electrons, liberated in liquid xenon due...
The Bubble-free Liquid Hole-Multiplier (Bf-LHM) concept has been proposed for the simultaneous detection of scintillation-photons and ionization electrons, in dual-phase noble-liquid detectors. In a simpler version of the Bubble-assisted Liquid Hole-Multiplier (Ba-LHM), the gas bubble trapped under a perforated electrode is replaced by a liquid-to-vapor interface located between two...
