Accelerator neutrino beams

“…While the first neutrino experiments at BNL and CERN did not in any way measure their neutrino flux, the follow-on experimental run at BNL [66] did so, and was the first attempt to measure a neutrino flux using the tertiary muons. Emulsions were placed in Figure 45: Emulsion measurements of muon fluxes in the steel shielding in the BNL neutrino experiment [66].…”

“…The first accelerator neutrino experiment [84,66] was a "bare target beam," meaning that the proton beam was delivered to the target, and the meson secondaries emanating from the target were permitted to drift freely away from the target. The only collimation or increase of flux is achieved by the relativistic boost of the secondaries in the forward direction.…”

“…The second BNL neutrino run did use an extracted beam [66,85], though still no focusing of the secondaries [146]. Extracted beams are the norm in today's experiments.…”

“…The CKP model [82] apparently dates back to cosmic ray work, and was used in neutrino beam simulation for the CERN-PS beam [202] (adapted by [206]) and by BNL [66]:…”

The NuMI Beam at FNAL and its Use for Neutrino Cross Section Measurements

“…Following experience at BNL [12], the CERN PS [13], and IHEP [14], we propose to use the three NuMI muon alcoves to measure the differential energy distribution of the neutrino flux. Unlike these previous beam lines, however, NuMI has only 3 muon alcoves (See Figure 1), so cannot perform a differential measurement by measuring the flux of muons above each of the 4, 8, and 18 GeV/c momentum thresholds of the alcoves (to be contrasted with the 7-12 muon stations in previous beam lines).…”
