Abstract

This paper describes the hardware and operations of the Neutrinos at the Main Injector (NuMI) beam at Fermilab. It elaborates on the design considerations for the beam as a whole and for individual elements. The most important design details of individual components are described. Beam monitoring systems and procedures, including the tuning and alignment of the beam and NuMI long-term performance, are also discussed.

In a very real sense, it takes a whole community of thought, planning, and effort to carry out an enterprise of the scope of the NuMI beam line. Our acknowledgement and thanks go out first of all to the support groups of the Fermilab Accelerator Division, including the Mechanical Support Department - and in particular the Target Hall Support Group, the Electrical Engineering Support Department, the Controls Department and the Instrumentation Department. We recognize and gratefully acknowledge the support of the Fermilab Particle Physics Division, who provided crucial design and support via its Mechanical Engineering and Alignment and Metrology Departments. The beamline could never have been completed or operated without the help of the Fermilab Facilities Engineering Services Section (FESS); we recognize their contributions with thanks. We extend our grateful acknowledgement to IHEP, Protvino, for its vital work in design and fabrication of the NuMI targets. The dedication, enthusiasm, and experience of the operations groups of the Fermilab Accelerator Division were essential in commissioning and running the NuMI beam, and receive our special appreciation. This work was supported by the US DOE, the United Kingdom STFC, the US NSF, the State and University of Minnesota, and Brazil׳s FAPESP, CNPq and CAPES. Fermilab is operated by Fermi Research Alliance, LLC under Contract no. De-AC02-07CH11359 with the United States Department of Energy.
