The EMPHATIC experiment at Fermilab measures the interactions that produce neutrinos in accelerator-based neutrino beams. The experiment operates at the Fermilab Test Beam Facility, where the interactions can be produced in a low-intensity, experimentally friendly environment. EMPHATIC completed an initial data run with a basic configuration in January, 2022. Data taking will continue in Summer, 2022.

Group members have participated in EMPHATIC data taking and simulation studies. Professor Fields serves as Software and Computing Convener for the EMPHATIC collaboration. EMPHATIC is planning a series of upgrades leading to EMPHATIC Phase 4, which will make a first-ever measurement of hadrons exiting a neutrino beam focusing horn. This work is supported in part by Prof. Fields’ Department of Energy Early Career award.
