Information on precautionary site access restrictions to Fermilab's Batavia site in response to coronavirus/COVID-19
We continue to review all events currently planned for the next sixty days and organizers will be notified if their event must be canceled, postponed, or held remotely. Please, check back on Indico during this time for updates regarding your meeting specifics.
As DOE O 142.3A, Unclassified Foreign Visits and Assignments Program (FVA) applies not only to physical access to DOE sites, technologies, and equipment, but also information, all remote events hosted by Fermilab must comply with FVA requirements. This includes participant registration and agenda review. Please contact Melissa Ormond, FVA Manager, with any questions.

indico search will be reestablished in the next version upgrade of the software:

MINERvA is about neutrinos

Our universe is awash in neutrinos. As you read this, millions of them pass right through you. Fortunately, they have negligible mass and neglible interactions with other matter, so you're OK. Negibile...but...that tiny amount of mass is enough to create mysteries about the nature of neutrinos and those tiny, rare interactions enable us to build dedicated detectors like MINERvA to study neutrinos.

We have some big questions about those tiny particles. Why do they have mass at all? What can "neutrino oscillations" tell us? What can we learn about how they interact with atomic nuclei?



Josh Klein, University of Pennsylvania


MINERvA is designed to focus on that last question, using the NuMI neutrino beam at Fermilab. Finding out will help physicists to understand their data much better when they complete the massive Deep Underground Neutrino Experiment (DUNE), which will use a massive neutrino detector way down in the Homestake Minemine at Sanford Lab in South Dakota to examine a neutrino beam from Fermilab in Illinois.



Don Lincoln, Fermi National Accelerator Laboratory


In the MINERvA masterclass, students and teachers make careful measurements of neutrino interactions with the carbon nucleus, pool their results, and discuss what they mean. Understanding those interactions is needed to help physicists understand the data that will come form DUNE.

Now let's go on to how we make the actual measurement of neutrino interaction data in MINERvA.
