    "abstract": "The optimization of the ballistic guide design for the SNS Fundamental\nNeutron Physics Beamline 8.9 A line is described. With a careful tuning of the\nshape of the curve for the tapered section and the width of the straight\nsection, this optimization resulted in more than 75% increase in the neutron\nflux exiting the 33 m long guide over a straight m=3.5 guide with the same\nlength.",
