The NuMI Beam at FNAL and its use for Cross Section Measurements

TL;DR

The paper reviews the design, operation, and initial results of the NuMI neutrino beam at Fermilab, highlighting its use in cross section measurements and flux determination techniques.

Contribution

It presents the NuMI beam's design, operational results from MINOS, and a novel method for direct neutrino flux measurement using muon flux data.

Findings

NuMI delivers a variable energy neutrino beam from 2 to 20 GeV.

Initial MINOS results demonstrate the beam's effectiveness for cross section studies.

A new technique for direct neutrino flux measurement using muon flux is discussed.

Abstract

The Neutrinos at the Main Injector (NuMI) facility at Fermilab began operations in late 2004. NuMI will deliver an intense muon neutrino beam of variable energy (2-20 GeV). Several aspects of the design and results from runs of the MINOS experiment are reviewed. I also discuss technique to measure directly the neutrino flux using a muon flux system at the end of the NuMI line.
