Abstract

Large-area, thin A1 foils were fabricated for use in particle beam neutralization experiments. The foils were used for survivability and lifetime studies when exposed to a H^- beam of 50 MeV with a peak beam-current density of 15.3 mA/cm². A range of foil thicknesses from 5 to 20 μg/cm² were required to determine the optimum foil thickness for converting H^- to H⁰. The technique and equipment used to fabricate thin A1 foils up to 25 cm in diameter are described in detail. Foil characterization including thickness, uniformity, purity, and structure before bombardment with the 500-MeV H^- beam is presented. Preliminary results from the H^- beam bombardment including neutralization results and foil survivability are described.
