First results on FHM — a Floating Hole Multiplier
Chepel, V.; Martínez-Lema, G.; Roy, A.; Breskin, A.A proof of principle of a novel concept for event recording in dual-phase liquid xenon detectors — the Floating Hole Multiplier (FHM) — is presented. It is shown that a standard Thick Gaseous Electron Multiplier (THGEM), freely floating on the liquid xenon surface permits extraction of electrons from the liquid to the gas. Secondary scintillation induced by the extracted electrons in the THGEM holes as well as ...
A next-generation liquid xenon observatory for dark matter and neutrino physics
Aalbers, J.; AbdusSalam, S. S.; Abe, K.; Aerne, V.; Agostini, F.; Ahmed Maouloud, S.; Akerib, D. S.; Akimov, D. Y.; Akshat, J.; Al Musalhi, A. K.The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon timeprojection chamber is the leading technology to cover the available parameter space for weakly interacting massive particles, while featuring extensive sensitivity to many alternative dark matter candidates. These detectors can also study neutrinos through neutrinol...
Solar neutrino detection sensitivity in DARWIN via electron scattering
Aalbers, J.; Agostini, F.; Maouloud, S. E. M. Ahmed; Alfonsi, M.; Althueser, L.; Amaro, F. D.; Angevaare, J.; Antochi, V. C.; Antunovic, B.; Aprile, E.We detail the sensitivity of the proposed liquid xenon DARWIN observatory to solar neutrinos via elastic electron scattering. We find that DARWIN will have the potential to measure the fluxes of five solar neutrino components: pp, 7Be, 13N, 15O and pep. The precision of the 13N, 15O and pep components is hindered by the doublebeta decay of 136Xe and, thus, would benefit from a depleted target. A high-statistics...
The XENON1T dark matter experiment
Aprile, E.; Aalbers, J.; Agostini, F.; Alfonsi, M.; Amaro, Fernando D.; Anthony, M.; Antunes, B. P.; Arneodo, F.; Balata, M.; Barrow, P.; Baudis, L.TheXENON1Texperiment at theLaboratoriNazionali del Gran Sasso (LNGS) is the first WIMP dark matter detector operating with a liquid xenon target mass above the ton-scale. Out of its 3.2 t liquid xenon inventory, 2.0 t constitute the active target of the dual-phase time projection chamber. The scintillation and ionization signals from particle interactions are detected with low-background photomultipliers. This ...
