Abstract:
This is NuMI Note B-700 (in PS form at "http://www-numi.fnal.gov/numinotes/public/ps/numi0700/numi0700.ps.gz"), but in PDF form. It is dated October, 2000. The Hadronic Hose was a proposed focusing system to be placed in the NuMI decay pipe. The hose, a single wire placed on the beam axis carrying a current of 1 kA, was expected to have two effects: 1) an increase in event rate in the MINOS detectors, and 2) an improvement in the near-to-far extrapolation of the neutrino spectrum. This note seeks to explain these two effects as well as provide a detailed comparison of the hose-on and hose-off fluxes for the three NuMI beams. Special attention is given to the low-energy beam.
