An interaction of slipping beams June 11, 2019 In particle accelerators, the greater a beam’s intensity, the more opportunities there are to study particle interactions. One way to increase the intensity is to merge two beams with a technique called slip-stacking. However, when combining them, the beams’ interaction may cause instability. A Fermilab scientist has created a successful model of the fraught dynamics of two particle beams in close contact, leading to smoother sailing in this area of particle acceleration.
Search for sterile neutrinos in MINOS and MINOS+ April 16, 2019 The MINOS+ collaboration at Fermilab collected data with a medium-energy neutrino beam from September 2013 to June 2016. The collaboration has exploited the data to set more stringent boundaries on the possibility of sterile neutrinos mixing with muon neutrinos.
CSI: Neutrinos cast no shadows February 4, 2019 The MINERvA neutrino experiment has a new crime scene investigation technique, one that takes a hard look at the traces that particles leave before fleeing the scene. Researchers used a new technique in a recent MINERvA neutrino investigation. And the new insights they gained on the workings of nuclear effects can help other neutrino experiments.
ArgoNeuT hits a home run with measurements of neutrinos in liquid argon February 1, 2019 Scientists on the ArgoNeuT experiment have developed a method that enables them to better distinguish the tracks that particles leave behind in liquid argon, as well as a way to better differentiate between signals and background. And thanks to the software’s great performance, ArgoNeuT will aid larger neutrino experiments in their quest to understand the nature of the subtle neutrino.
Identifying lower-energy neutrinos with a liquid-argon particle detector January 9, 2019 For the first time, scientists have demonstrated that low-energy neutrinos can be thoroughly identified with a liquid-argon particle detector. The results, obtained with the ArgoNeuT experiment, are promising for experiments that use liquid argon to catch neutrinos, including the upcoming Deep Underground Neutrino Experiment.
