    "abstract": "A neutrino horn based on a solenoid lens offers several potential advantages\nover a conventionl toroidal horn when used with a multimegawatt proton source\nto pursue studies of CP violation in neutrino oscillations. 1) A solenoid horn\ncan produce a neutrino spectrum with a sequence of peaks at momenta P = P_0 /\n(2 n + 1), which has the same form as the sequence of momenta at which the\nneutrino oscillation probability is maximal for a fixed distance from source to\ndetector. 2) The neutrino flux is a roughly equal mixture of neutrinos and\nantineutrinos. 3) Rates of electron neutrinos from muon decay are suppressed\nrelative to those in a broad-band neutrino beam. 4) A solenoid magnet has its\ncoils far from the axis where the target is located, and hence the coils are\nmore readily protected from radiation damage. 5) A solenoid magnet is readily\ncompatible with a liquid metal target, as will be needed for use with very\nintense proton sources. 6) A solenoid magnet is a DC device, and hence not\nsubject to pulse fatigue as for a conventional toroidal horn.",
