SUMMARY:VIRTUAL INPA SEMINAR | Luca Pagani (UC Davis )
DESCRIPTION:Speaker: Luca Pagani (UC Davis) \nTitle: First Results From The ARTIE Experiment \nAbstract: \nA measurement of the transmission coefficient for neutrons through a thick (~3 atoms/b) liquid natural argon target in the energy range 30-70 keV was performed by the Argon Resonance Transmission Interaction Experiment (ARTIE) using a time of flight neutron beam at Los Alamos National Laboratory. In this energy range theory predicts an anti-resonance in the 40-Ar cross section near 57 keV\, but the existing data\, coming from an experiment performed in the 90s (Winters. et al.)\, does not support this. This discrepancy gives rise to significant uncertainty in the penetration depth of neutrons through liquid argon\, an important parameter for next generation neutrino and dark matter experiments.In this talk\, the first results from the ARTIE experiment will be presented. The ARTIE measurement of the total cross section as a function of energy confirms the existence of the anti-resonance near 57 keV\, but not as deep as the theory prediction. \n\n\n\nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/96839979915pwd=VXIvTVFiSDN4cHdFYJTb0hiTUhWUT09 \nMeeting ID: 968 3997 9915 \nPasscode: 273612
