Measuring the α-particle charge radius with muonic helium-4 ions
Krauth, Julian J.; Schuhmann, Karsten; Ahmed, Marwan Abdou; Amaro, Fernando D.; Amaro, Pedro; Biraben, François; Chen, Tzu-Ling; Covita, Daniel S.The energy levels of hydrogen-like atomic systems can be calculated with great precision. Starting from their quantum mechanical solution, they have been refined over the years to include the electron spin, the relativistic and quantum field effects, and tiny energy shifts related to the complex structure of the nucleus. These energy shifts caused by the nuclear structure are vastly magnified in hydrogen-like s...
Intrinsic backgrounds from Rn and Kr in the XENON100 experiment
Aprile, E.; Aalbers, J.; Agostini, F.; Alfonsi, M.; Amaro, Fernando D.; Anthony, M.; Arneodo, F.; Barrow, P.; Baudis, L.; Bauermeister, BIn this paper, we describe the XENON100 data analyses used to assess the target-intrinsic background sources radon (222Rn), thoron (220Rn) and krypton (85Kr). We detail the event selections of high-energy alpha particles and decay-specific delayed coincidences. We derive distributions of the individual radionuclides inside the detector and quantify their abundances during the main three science runs of the expe...
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 ...
