Determination of the neutrino fluxes in the Brookhaven wide-band beams

The neutrino fluxes φ(E( $ν_{μ}$ )), φ(E(ν $¯_{μ}$ )), and φ(E( $ν_{e}$ )) in the Brookhaven Alternating Gradient Synchrotron wide-band beams have been determined by measurements of quasielastic interactions observed in a massive, high-resolution detector. These fluxes are accurately reproduced by Monte Carlo calculations.

The literature on neutrino beams and magnetic-horn design is sparse. A high-intensity neutrino beam was described in M. Giesch et al., Nucl. Instrum. Methods 20, 58 (1963), where an estimate of the expected neutrino flux was made. The neutrino beam at the Brookhaven AGS has used a horn geometry which was initially described in R. Palmer, Proceedings of an Informal Conference on Experimental Neutrino Physics, CERN, 1965, edited by C. Franzinetti (CERN Report No. 65-32, 1965).
