A recent concept was proposed and investigated for the combined detection of radiation-induced ionization electrons and primary scintillation photons in noble liquids. This so-called bubble-assisted Liquid Hole-Multiplier (LHM) consists of a thin perforated electrode (GEM or THGEM), immersed in the liquid - with a stable bubble of the noble gas trapped underneath; the electrode’s top surface is optionally coated with a CsI UV-sensitive photocathode. Ionization electrons, and UV-induced photoelectrons from the CsI surface are collected into the holes and cross the liquid-gas interface into the bubble; they induce respective electroluminescence in the bubble, of which the photons (~400/e/4p) are detected by a SiPM array. We will present the new concept, the LHM-SiPM performances in liquid xenon and discuss potential applications.
