Abstract

We consider transport of light, neutrons, or any uncharged particles in a straight duct of circular cross section. This problem first came to fashion some 30 years ago when Pomraning and Prinja formulated their so called "pipe problem". In the years to follow, investigators applied essentially every known method of numerical solution, including MMRW's Wiener-Hopf - except possibly one. This presentation concerns that particular numerical solution, which arguably seems to be the most efficient of all.
