The plasma lens concept is examined as an alternative to focusing horns and solenoids for a neutrino beam facility. The concept is based on a combined high-current lens/target configuration. Current is fed at an electrode located downstream from the beginning of the target where pion capturing is needed. The current is carried by plasma outside the target. A second plasma lens section, with an additional current feed, follows the target. The plasma is immersed in a solenoidal magnetic field to facilitate its current profile shaping to optimize pion capture. Simulations of the not yet fully optimized configuration yielded a 25% higher neutrino flux at a detector situated at 3 km from the target than the horn system for the entire enegry spectrum and a factor of 2.47 higher flux for neutrinos with energy larger than 3 GeV. A major advantage of plasma lenses is in background reduction. In anti-neutrino operation, neutrino background is reduced by a factor of close to 3 for the whole spectrum, and for and for energy larger than 3 GeV; neutrino background is reduced by a factor of 3.6. Plasma lens advantages are due to: larger axial currents, high signal purity: minimal neutrino background in anti-neutrino runs. Additionally the lens medium consists of plasma, consequently, particle absorption and scattering is negligible. Withstanding high mechanical and thermal stresses in a plasma is not an issue.

Preliminary ideas for novel pion capturing and focusing schemes are presented in this note. Although extensive simulations are needed before any conclusions can be drawn, a basic argument (plasma lenses can support larger currents; can shape discharge profile) is presented that suggests that Z pinches and spark channels deserve a further, more serious consideration for possible use in the proposed BNL super neutrino facility. A Z pinch or a Z channel combined with an intense relativistic electron beam, or the use of inverse pinch configurations to capture and focus both positive and negative pions into separate regions in space is an intriguing possibility that may benefit the muon collider.
