[en] The report overviews preliminary results on the feasibility to produce a neutrino beam based on the U-70 proton synchrotron at Protvino for a very long baseline experiment with the deep water ORCA detector in the Mediterranean Sea.

[en] The SPS muon beam, recently upgraded for the Spin Muon Collaboration experiment, is described. The basic concepts of the beam design are presented. The measured beam flux and muon halo rates, spot sizes and average muon polarisation are reported and the observed performance is compared with Monte Carlo simulations. (orig.)

[en] We have developed a new focusing system for conventional neutrino beams. The 'Hadron Hose' is a wire located in the meson decay volume, downstream of the target and focusing horns. The wire is pulsed with high current to provide a toroidal magnetic field which continuously focuses mesons. The hose increases the neutrino event rate and reduces differences between near- and far-field neutrino spectra for oscillation experiments. We have studied this device as part of the development of the Neutrinos at the Main Injector project, but it might also be of use for other conventional neutrino beams
