DESCRIPTION:Speakers: Valerio D'Andrea (UnivAQ & LNGS)\nThe ABALONE is a n
 ew type of photosensor produced by PhotonLab with cost effective mass prod
 uction\, robustness and high performance. This modern technology provides 
 sensitivity to visible and UV light\, exceptional radio-purity and excelle
 nt detection performance in terms of intrinsic gain\, afterpulsing rate\, 
 timing resolution and single-photon sensitivity.\nThe new hybrid photosens
 or\, that works as light intensifier\, is based on the acceleration in vac
 uum of photoelectrons generated in a traditional photosensor cathode and g
 uided towards a window of scintillating material that can be read from the
  outside through a silicon photomultiplier (SiPM).\nIn this contribute we 
 present the characterization of the ABALONE operated at room temperature f
 or the evaluation of the gain as function of the electric field\, the resp
 onse in time and the single-photoelectron spectrum. In order to better und
 erstand the experimental results\, we performed the simulation of the phot
 osensor by reproducing the electrostatic field\, by tracking the accelerat
 ed photoelectrons and their interaction in the scintillation window.\nSoon
  we plan to operate the ABALONE in a Xe environment. Details of future tes
 ts and possible applications in the context of next-generation astropartic
 le physics experiments (e.g.\, DARWIN) will be also discussed.\n\nhttps://
